Do Bacteria Have Cytoplasm: Why, How and Detailed Insights

Cytoplasm is any solution with thick consistency filled up in each of the cell and is thus enclosed within the cell membrane.

In concerned with the question for do bacteria have cytoplasm, the answer is yes. They are just like the cells of eukaryotes having a cytoplasm which is one among the organelle in the eukaryotes.

There are other organelles in the bacteria which include the plasma membrane the ribosomes and the cytoplasm. There are a lot characters that separate the eukaryotic cell from the circular DNA that is in the nucleoid, it also lacks few membrane surrounded organelle.

Cytoplasm is also called protoplasm of the bacterial cell is like a gel just like matrix made of 80% of the water enzymes, gases, the waste, inorganic ions and have compounds that have less molecular weight and have structures of cell like that of the chromosomes, ribosomes and the plasmids.

In some of the cells which also include the bacterial cell, also have a cell wall. In the bacteria, the cytoplasmic membrane involves the cytoplasm and is situated having in the cell wall of the bacteria. The membrane of the cytoplasm is also called plasma membrane and is simply the cell membrane.

Do all bacteria have cytoplasm?

Cytoplasm is also found in the cells of eukaryotes and comprises of many of the wastes and the ions needed for the cell.

This is not typical of all the bacteria but some of the microorganism does have the intracellular membranes along with many of the extensions like the cytoplasmic membranes.

The cell of the bacteria does lack a nucleus that has a membrane. The hereditary products of the bacteria are naked and are inside the cytoplasm. The only type of organelle that the bacteria have is the Ribosomes.

There is a part called the nucleoid that indicates the place of the cytoplasm where the DNA is kept and is actually single and the chromosome are of circular type. The bacteria are also found in colonies and unless till then they do have single cells.

The bacteria are called to be the cells of ancestry and reproduce by the process of binary fission that gets in process with duplicating the genetic substance and then making it sure to split to make two daughter cells that are identical to that of the parent.

Why bacteria have cytoplasm?

The interior of bacteria is made up of proteins and phospholipids they helps cell regulation throughout.

The part for do bacteria have cytoplasm is yes and the protoplasm or the cytoplasm inside them helps in for the metabolism, the growth of cell and getting the process of replication maintained.

It is a matrix structure looking like a gel and is made of the wastes, the gas, nutrients, the water and the enzymes which also have the structures for plasmids, the ribosomes and the chromosome present in them. The cytoplasm is enclosed within the cell envelope.

The cell envelopes entrap all the components of the cytoplasm and also it. Unlike all the true cells the bacteria have no confined membrane nucleus with a chromosome DNA stand which is localized but is not contained in the area of the cell known as nucleoid.

All the components of the cell are scattered in the entire part of the cytoplasm. Just like the chromosomes; the plastics are composed if the DNA material that is circular. They are not a part for reproduction.  The plasmids do get to replicate on it and is not concerned for survival.

The membrane of the cytoplasm is a trait for the bacteria structure and also shares it with the other cells that are living and also acts as a barrier that gets them to allow having a selective communication with the surrounding. The membrane is quote organized and are not symmetric from both ends with have separate functions.

How bacteria have cytoplasm?

The boss of the cell that directs the functions inside is the nucleus with water being the major part of the cell.

The cytoplasm is mostly of a gel like material inside the cell that is composed up of the organelles except the nucleus and the semi fluid which is the cytosol. The cytoplasm has a lot going on.

The cytosol is regarded to be the crowded part where many of the actions do take place. The cell is kept alive for many of the organelles like that of the endoplasmic reticulum, the mitochondria, the Golgi apparatus with having special functions as well.

There are few molecules that keep on shuffling between the organelles and the proteins that are made to synthesis. ATP is the storage for energy which is made and the waste is discarded. The cytoplasm also has cytoskeleton made of the protein fibers.

There are many ions that help in for osmosis and is mostly for keeping the cell from getting swelled up with water and the leaves so that the cell does not get to dry up or malfunctions. Glycolysis also does take up in here and there is also the provision for chemical signal transmission.

Do bacteria have cytoplasmic membrane?

There is a presence of 70s ribosome in the cytoplasm of the bacteria and is also much packed up with also many granules.

The answer for do bacteria have cytoplasm is yes along with it also having a cytoplasmic membrane which is made up of the phospholipids. The composition of the cytoplasmic is the proteins and lipids.

The basic components that make the lipid layer of the cytoplasmic membrane is the phospholipids that vary within the length of acyl chain, getting them saturated and making a branch that shall carry the main groups and may vary in the charges present along with the size.

The cells can be made of many materials and one of the most general is the cell membrane that gets to separate the materials of the cell from the surrounding of cell. All of the cells have the cell membrane and they come with slight variations with some cells having cell wall.

Most of all the metabolic process takes place in the cytoplasm of the bacteria and also have inclusions like the ribosomes, the cytoplasmic granules, the plasmids. The ribosomes are actually made up of 30% of the ribosomal proteins and are if 70% ribosomal RNA. The association of these needs the help and involvement of magnesium.

Where is the cytoplasm in a bacterial cell?

Cytoplasm of bacteria includes the reserves like the cyanophycin, granules, carboxysomes, glycogen and the polyphosphate granules giving buoyancy to cell.

Within the cells of the bacteria, the cytoplasmic membrane gets to cover the cytoplasm and is situated within the cell wall of the bacteria. The cytoplasmic membrane is also called the plasma membrane or even is refereed as cell membrane.

The cytoplasm of the bacteria has 70s ribosomes within one single subunit having a molecule of 16s ribosomal RNA and one large unit having double molecules of 23 and 55 ribosomal RNA. The ribosomes are related to get the genetic material translated from molecular level. the number of ribosomes in prokaryotes and eukaryotes differ.

Ribosomal convert the language of nucleic acid to the building block of proteins which is the amino acids. Proteins are the ones that are used to serve all the functions within a cell and a living being. They have gas vesicle that is hollow and is spindle like and is composed of proteins and planktonic bacteria.

The cytoplasm has a lot of organelles which have membrane and also includes many of the membrane that have less inorganic and the organic stuffs and is called the inclusion bodies. Inclusion body is the place where the membrane differs from the unit membrane being typical.

What is cytoplasm of bacteria made of?

The cytoplasm is also referred to as the protoplasm and the cell of the bacteria has it in form of a gel matrix which is made up of 80% water.

The cytoplasmic membrane or the plasma layer of the bacteria is made up of the phospholipid bilayer and is set for all the basic functions if the cell membrane likes being a permeable membrane for many molecules.

They serve as the direction to many of the molecules that get to transport in the cell. Along with this usage, the membranes of the prokaryotes also serve as the site for energy storage where it is the site where the force for proton motive is made.

Unlike the eukaryotes the membrane of the bacteria with some of the exceptions in methanotrophs and mycoplasma on a basic level do not have sterols. There are many small organisms that do have compounds that do relate structurally and are called hopanoids.

In the bacteria having the cytoplasm there can be seen traces of few fatty acids inside the membranes. On addition with all the unsaturated and saturated fatty acids that are typical the cytoplasm of bacteria also has fatty acids with add on to methyl the cyclic ones that are even and hydroxyl.

Do Bacteria Have Lysosomes: Why, How and Detailed Insights

Purp d winogradsky 300x248 1

A lysosome is a organelle which is enclosed my membrane and also has many digestive enzymes with also being involved in many process and are the subcellular parts found in eukaryotes.

The bacteria do have a complex cell wall and with the question of do bacteria have lysosomes the bacteria have no membrane bound organelles and thus no lysosomes as well but do have granules.

The cell wall of prokaryotes has peptidoglycan and also has many small ribosomes inside the cytoplasm. DNA is the genetic material in them inside the cytoplasm and organized in the chromosome and inside the plasmids.

There are presence of messenger RNA, transfer RNA and ribosomal RNA. They have flagella for locomotion which is rigid and have spirochetes that have axial filaments.

The bacteria are quite of the simple one that have not much and does not include any organelles having membrane or the nucleus. They still do have many cell structures that help in the life support. They include the flagellum, the pili, the ribosomes and the cell envelope.

In which organisms are lysosomes found?

The lysosomes are also referred to be the bags having destructive property as they have many of the digestive enzymes.

They are found in the entire cell of the eukaryotes that are like animals. They are much in common in the animal cells as the animals absorb and taken in food which needs the enzymes inside the lysosomes.

They need the lysosome enzyme to get them digested and then use them as energy in form of food. If there is something that burst inside the lysosomes releases the digestive enzymes that helps in getting the cells to digest and helps in the death of the cells which is harmful.

Lysosomes are involved in revival, getting things tired and sensing the presence of nutrient. they are very capable and dynamic when it comes fission and fusion membrane with plasma and organelles. A special group of lysosomes is seen in high eukaryotes.

Why don’t prokaryotic cells have lysosomes?

With the answer to do bacteria have lysosomes which are one among the organelles found in animal cell the answer is no.

The cells of prokaryotes do not have lysosomes. The reason for this is that the lysosomes are made from the endoplasmic reticulum along with the Golgi bodies which are said to be the membrane organelles.

The cell of the prokaryotes does lack all the organelles that need to have a membrane bounded with them that shall include the mitochondria, the nuclei, the chloroplasts and the lysosomes. Both of the cells of the eukaryotes and the prokaryotes have ribosomes.

The ribosomes are the organelles that do not have any membrane around it and thus are in general made up of ribosomal RNA. The cells of the prokaryotes need them for energy and getting to synthesize the proteins needed for their growth.

Lysosomes are the ones that are seen in almost all the eukaryotes which are animals. They are most seen in the cells of the plants as they have cell walls and are mostly tough to keep the bigger or outside material that shall be digested by the digestive enzymes of the lysosomes within the cell.

Do photosynthetic bacteria have lysosomes?

There are many numbers of tiny ribosomes that are present in the cytoplasm for they do no need any membrane.

In all of the eukaryotes that are phototrophic the process of photosynthesis takes place within the chloroplast which is an organelle that arose inside the eukaryotes by the process of endosymbiosis of the photosynthetic bacteria.

The prokaryotes that are actually capable of getting the process of photosynthesis done by them is called the photosynthetic bacteria. On regards with do bacteria have lysosomes it is not needed for the process of photosynthesis or its survival. They are also seen in the freshwater, the soil and the rocks.

These are mostly found in the rivers, the lakes, the soil the oceans and the sludge that are usually seem to be activated. Their habitat is very much general and can grow in any type of area around the globe.

All of the bacteria, the chloroplasts and the mitochondria are same in their size. The bacteria do have the ribosomes and the DNA the ribosomes which are same to that of the chloroplast and the mitochondria. Both of the eukaryotes and prokaryotes have ribosomes despite the prokaryotes lagging all of the membrane bound organelles.

Why are lysosomes absent in bacteria?

The cells of bacteria have no organelles that have membrane covering them. Thus they have their digestion extracellular.

The bacteria do keep a breakdown for the molecules inside the media covering the bacteria and then get to absorb the materials. As they do not have membrane bound organs they also have no lysosomes.

The organelle lysosomes cannot digest their own self. Most of the proteins that are seen in the membrane do have lot of high content of the sugar and the carbohydrates present as a group as the groups and all the digestive enzymes are incapable of getting themselves digested.

These organelles is said to have 60 different types of enzymes and almost 50 membrane proteins. The term for it is only applicable to the animal’s vesicular organelles and vacuoles are said to be for the plants.

FAQs- (Frequently Asked Questions)

What is the work of lysosomes?

A lysosome is used up break down the extra or the ruined parts of the cell. They are seen in animal cells.

They can also be used to destroy the bacteria or any other microbes. If the cell is already damaged and cannot be repaired the lysosomes are capable of helping it and then having it self-destruct called the programmed cell death or the apoptosis.

How to pathogen enter lysosomes?

The lysosomes at the end of endocytosis acts as safe in getting to prevent the pathogen from getting the cytoplasm degrade.

The pathogens do take over the endocytosis paths like the pinocytosis in concerned with the cell entry. The lysosome gets to prevent the entry inside the cell by getting the biomolecules hydrolyzed for the pathogen.

It is also needed for many strategies for replication and includes the reduction of lysosome activity resulting in microbe activity in including the HIV. Also, in addition to many toxins like the cholera they takeover the endosome path while getting to evade the degradation.

Is Cyanobacteria Unicellular Or Multicellular: Why, How And Detailed Insights

cy

Cyanobacteria are of the phylum from Gram negative bacteria and are also called Cyanophyta.

With the question for is cyanobacteria unicellular or multicellular, cyanobacteria are the most diverse type that can range from being unicellular to multicellular and do have filaments.

They do take up energy from the process of photosynthesis. The name of this means the colour blue in ancient Greek. The name thus given to these is also blue green algae. The botanist does not agree on giving the term algae to the eukaryotes but cyanobacteria are exception.

They are seen in the fresh water or even on the terrestrial lands. The cyanobacteria generally use the photosynthetic pigments, like the carotenoids and the phycobilins and other form of the chlorophyll that helps in absorbing the energy form the sun.

Cyanobacteria do mark good variety of morphology from the unicellular colonial to the filaments. The filamentous forms do show up cell differentiation like the heterocyst, the akinetes and the hormogonia. All of these together have connections and are termed to be the first mark of multicellularity.

Where is Cyanobacteria found?

They are much diverse and large in their phylum and are the photoautotrophic prokaryotes.

They are seen in almost all places. The sea spray consists of the marine microbes that includes the cyanobacteria and can be swept high inside the atmosphere which turns them into aeroplankton and can move anywhere. 

They do often inhabit in colonial aggregates that can take up thousands of forms. They do have filaments dominating the upper area and is found in much of the extreme surrounding conditions like in the hot springs, the hyper saline water in polar areas and the dessert.

They are microscopic in nature and are in general in all types of aquatic form being their natural habitat. While in the fresh water, marine or in the mixed up ratio of marine and fresh, these do have one cell and also use up sunlight to make their own food.

They are actually optimized for all the next to be place conditions of having less oxygen. Some of them are used for nitrogen fixing and some live inside the water and the moist soils with being free or having a symbiotic equation with the fungi or the plants.

Are all cyanobacteria unicellular?

The cyanobacteria may have many sheaths to het the filaments or the cells from the colonies to bind to themselves.

Some of the cyanobacteria can be cells that do free live and can be unicellular like the Prochlorococcus, the Synechococcus, the Crocosphaera but also some of them do show symbiotic links with many haptophyte alage like the Coccolithophores.

The marine life cyanobacteria are quite extensive and do have high blooms with having their appearance in blue green or scum. The blooms can be toxic and can quite lead to the closure of the waters with many of the marine one being vital parasites of the unicellular range.

With the fact of is cyanobacteria unicellular or multicellular, the symbiotic state clears it all while getting itself linked up with the rest organism for its survival.

Many of the species of this can also glide up in the way as the cell moves differing from the movement of swimming or crawling relying on any outside organelle change and take place in the presence of substrate. The ones that do glide through the plants do possess filaments that help them move.

The gliding of the filamentous bacteria seems to be energized by a mechanism called the slime jet where the cell do release a gel that gets itself expanded fast and helps the, in getting itself hydrated also giving them a force of propulsion with some of the unicellular ones also using it.

The bacteria can enter into the plants via the stomata and then get to colonize the inter space that shall form loops and many inner coils. Some of them colonize the roots of plants while some target the root system.

Why are cyanobacteria multicellular?

They are on among the unicellular ones that are the oldest and did make it up gradually into many forms consisting of colonies as well.

The cyanobacteria are the largest with being the diverse prokaryotic phylum, along with the morphophytes that are of all range and varies from being unicellular to the multicellular one and also being filamentous.

 Some of the cyanobacteria are able to get the nitrogen from the surrounding fixed and get them converted into the forms that can be used by the animals and plants. They also have seemed to raise the level of oxygen in the atmosphere by 2.45 billion and give the base of aerobic evolution.

With is cyanobacteria unicellular or multicellular, the species of the cyanobacteria are all filamentous or form colonies. The ones that are multicellular have developed many cell having separate functions. Some of the cells do carry on photosynthesis while other respiration and other absorb nitrogen.  

The cyanobacteria get their energy from the process of photosynthesis while getting to absorb the light as the source of energy and use the nitrogen form atmosphere to make amino acids which are the protein building blocks. Yet, this can also lead to make trouble for getting to exchange and communicate materials.

Filamentation

FAQs-(Frequently Asked Questions)

Why are cyanobacteria not said to be multicellular?

This is because as the bacteria do not have any of the cell compartments thus they are said to be prokaryotes even after not having the same functions as the organism being multicellular.

Are the protists unicellular or multicellular?

Any group members of the protists that are eukaryotes are basically termed as the unicellular microscopic ones.

They can share any physical attributes or morphology same to that of the plants or the animals or even both yet they are unicellular. The very vast part of the protists is unicellular having many cells and does from up colonies.

How to cyanobacteria respire?

The process of respiration in these can take place inside the membrane of thylakoids along with photosynthesis sharing the same place for respiration.

The class of cyanobacteria uses up several protein pairs to perform aerobic respiration which marks the trait for being independently getting acquired in each of the class. It is thus consistent with the rise of the oxygen that takes place after the divergence.

Do Prokaryotes Have DNA Replication: Detailed Insights and Facts

dna1

Prokaryotes are the one that lack a nucleus and also the rest of the organelles. They are mostly single celled and are small.

With the question for do prokaryotes have DNA replication, the answer is yes. Inside the prokaryotes there is just a single origination point where replication takes places in two paths and is always at same time. It takes place inside the cytoplasm.

The replication in DNA for the prokaryotes is the process where the organism do duplicate the DNA in a on other copy and is passed on to the daughter cells. It is usually generalized for E.Coli but is also shown by bacteria.

Replication of DNA is however a bi-directional one and generates at the one point for the purpose of replication. It also has there steps that includes the initiation, the elongation and the termination.

What is DNA replication in prokaryotes called and why?

The time when the prokaryotes do DNA replication, there is a theta like structure seen at the site of replication.

The process for DNA replication in the prokaryotes is called as Theta replication. The reason for this is that during the process it makes a resemblance of a Greek letter called theta (θ).

A theta structure is an intermediate structure that is formed during the process for replication of DNA that is circular. There is an unwinding if the helix that is double stranded and makes a loop which is called the replication bubble.

In the theta replication, the DNA which is double stranded unwinds itself at the site of replication that helps makes the stands for nucleotides helping them to serve as the templates which shall be the base for DNA synthesizing.

While the unwinding takes places there is a formation of loop and s called the replication bubble. The process for unwinding may take place in both the ends or in one side of bubble that makes it quite large. The process for DNA replication on both the strands goes equal with unwinding.

The point where there is unwinding, the pace where the strands for nucleotides gets separated from the circular DNA helix that is double stranded is termed as the replication fork.

Where does DNA replication occur in prokaryote?

Inside the prokaryotes there is only one point for replication where the process takes place in two separate paths in the similar time. DNA replication takes place before binary fission.

The answer for do prokaryotes have DNA replication is yes and the process of DNA replication for these organism takes place inside the cytoplasm of the cell. The DNA replication is seen inside the nucleus of the cell. 

The process for DNA replication occurs prior to that of cell division which helps in ensuring that both the cells do receive the same copy of the genetic substance from the parent. The division in animals have different time period of completion.

The division in prokaryotes and eukaryotes do have similarities and differences for the size and the molecules being complex. The cells of the prokaryotes are quite in the structure with only little DNA and no organelles or nucleus.

The replication for DNA can also take place in a test tube and thus this process can be called to be self-replication. The mechanism for the process of DNA replication inside a test tube is the same as the way in the eukaryotes and the prokaryotes and mitosis or meiosis in the eukaryotes.

How do prokaryotes replicate?

The replication in DNA is so that there is a duplicate formation of the genetic material from the parent to the other getting passed to the daughter cells.

But on the other hand the reproduction process of the prokaryotes takes place via the process of cell division which is known as binary fission. It is just like the process of mitosis in the eukaryotes.

This procedure includes copying of the chromosomes an also separating of a single cell into two others. The process for binary fission is asexual mode of reproduction which involves no egg or sperm making.

There is no generation of sperm or egg or any type if mixing of the genetic material from the two organisms. There is an exception for a rare type of mutation or DNA sequence change, where the binary fission makes the daughter cells that are same to the mother cell.

The reproduction in prokaryotes is much faster than compared to the eukaryotes. The speed of division can be mentioned in regards to generation time or the time length from the making of one generation to the birth of the next one.

Well, with regards to do prokaryotes have DNA replication, not can all bacteria be quick in reproduction with some of that are pathogenic as well. Mycobacterium tuberculosis has a generation time for about 12 hours. They are still the fast multipliers in natural conditions and test tub in lab.

How do prokaryotes make DNA?

The reproduction in the prokaryotes is asexual and takes place generally by the binary fission, they have circular chromosome and do not go for mitosis.

The chromosome or the DNA of the prokaryotes is replicated and there are two copies as outcome which is different from each other for the reason being the mobility of the cell membrane to which they are adhered.

Prokaryotes are the organisms that often do lack any of the organelles and also the nucleus. But, they do have DNA which is circular and is stored in the central part of the call which is called the nucleoid that s in turn surrounded by the nuclear membrane.

The prokaryotes have a singular chromosome which is actually single and usually occupies a region of the cytoplasm and is called the nucleoid. They also include of many rigs that are small in size and are usually double stranded with having extra chromosome and are the plasmids.

A phenomenon in the prokaryotes is referred to as supercoiling that helps the organism in reducing the DNA and allows them for more space and so that the DNA can be kept packed easily. This is quite plectonemic as the chromosomes are actually small.

What are the characteristics of prokaryotic DNA replication?

The deoxyribonucleic acid and the chromosome in the prokaryotes is circular in shape with being located inside the cytoplasm of the cell.

The replication of the DNA in the prokaryotes is bi directional and generated from the single place of origin for replication. It takes place in the cytoplasm and occurs in the direction of 5’to 3’ direction.

 The stands of the DNA are considered individually and are made in several directions that are to be followed. This gives them a lead and while generating of the lead it also makes a lagging strand.

The replication of DNA is actually a semiconservative process. It means that the each of the DNA stand is a double helix one and works as a template for getting a new one synthesized. This method takes it from one molecule to start with and then ending up for two daughter molecules.

The two new daughter molecules that are formed as a result are also double helix and have one old and one new strand carrying the copy of the genetic material from the parent. There is also formation of replication fork.

Why do prokaryotes only have one origin of replication?

In the prokaryotes, there are there vital types of polymerases that are called DNA pol I, DNA pol II, DNA pol III. These have only one site of replication origin.

The cell of the prokaryotes is much smaller and thus can get away with any process having only one site of origin. Mostly all the prokaryotes do have a single place of replication however the rate for the replication is also very high.

In the prokaryotes, the single place of replication does have many of the adenine and thiamine bases that have the hydrogen bonds on the weaker sides than compared to the guanine and cytosil pairs. It helps in making the DNA strands easier to separate.

There is an enzyme that is called the helicase that helps in unwinding of the DNA by getting the hydrogen bonds to break amongst all the nitrogenous base makings. With concern to this, eukaryotes and prokaryotes that different replication site.

What is unique about prokaryotic DNA replication?

There is only one point of replication of DNA for the prokaryotes which takes place in two directions and is concerned within the cytoplasm.

The uniqueness given by the prokaryotes are concerned with the replication site. The site of replication in length is approx. 245 bases in pairs in length and is quite in rich within Adenine and Thiamine.

The sequence of AT together is seen by some of the proteins that bind to the sites. There is an enzyme known as the helicase that helps in getting the DNA unwind itself with breaking of the hydrogen deals in the nitrogen pairs. The strands help in preventing the rewinding of the double helix.

After the DNA keeps on opening, the Y-shaped structures are called to be the replication forks. They are located in the site of replication and are usually bi directional as they proceed. There is also a single strand that binds the proteins which covers the single strands of DNA.

Another enzyme linked with it is the DNA polymerase II that adds up to the nucleotides taking each at a time on the DNA chain that is growing. The nucleotides that are added need energy, this energy is taken from the nucleotides that have phosphates linked with them and are three in number.

Is prokaryotic DNA replication unidirectional?

There is only one site for the part of replication for the concern in prokaryotes still the replication is rapid.

In regards with the prokaryotes the DNA replication process is nit unidirectional. They have only single site of origin for the purpose of replication and is bidirectional.

Bidirectional replication of the DNA is any mechanism that is ensured to all the eukaryotes and mostly all the prokaryotes cells. The replication that is unidirectional is rare and do is seen to take place only in very limited number of the cells of prokaryotes.

The reason for the DNA replication to be bidirectional is that the enzymes related to unwinding of the DNA called the DNA helicases cause the two of the parent DNA strands to get itself unwinded and then separates from one to the other in both ways at the same site that forms the Y-Shaped replication forks.

How many origins of replication do prokaryotes typically have?

The eukaryotes cells have DNA replication that is needed during the formation of replication forks with the prokaryotes being rapid.

There are three polymerases that has the single site for replication on the specific chromosome which is similar to many prokaryotes. It is approx. of length of 245 base pairs in length and is quite rich in AT pairs.

The cells for the prokaryotes uses up the single variety for the rapid replication propose. There are actually approx. about 350 origins of replication in the entire the genomes.  On the contrary there is an estimation of 40,000 to 80,000 origins that get distributed via the human genome.

The replication in bacteria is regulated at the time of initiation stage. DNA is hydrolyzed into inactive by RIDA which is the regulator inactivation of the DnaA that gets converted to DnaA-ATP by the DARS. The complementary strand for 3’ to 5’ gets synthesized all time as the polymerase can add to nucleotides.

There are the three models that can be suggested for DNA replication. These are dispersive, conservative and semi-conservative. The method that is conservative suggest that the parental DNA and remains together and gets to form the parental DNA along with it together.

Is prokaryotic DNA replication conservative or semiconservative?

The genetic material needs to get itself replicated to get assure the policy for hereditary.

It has already been seen that DNA is replicated by the process which is semi conservative in the WT-4 cells that grow in 34 degrees Celsius or at the 38.5 degree covering the entire logarithmic phase and gets into the stationary phase.

The base system applied for the process of DNA replication is same from the microbes to the eukaryotes, there are a lot of variations that to make up the final product mode. The microbe DNA replication for some of the microbes do have ailments that are single stranded.

For this way, the replication of the genetic product shall be kept in consideration through the complementary strand inside the intermediate step for double stranded in the form of replication. All the form of DNA does need a region for replication to get the strands separated.

A very general and common character for the origins responsible for the separation of strands in the semiconservative replication process is that they are much rich in the A=T. Not so common about it is the prevalence of the G over the C and the T over the A in the prokaryotes which is also the leading strand.

Why is DNA replication faster in prokaryotes than eukaryotes?

The process of replication is much fast in prokaryotes than the other. Some of the bacteria take 40minies while animals cell take 400 hours.

The DNA polymerase is much rapid in regards to the base that is replicated per second; however it does have only one origin of replication. Eukaryotes have distinct way for replication.

On the other hand there are many site for replication in the eukaryotes, there are many parallel running DNA polymerases that make up the process of DNA replication easy and much faster in the eukaryotes.

The reason for the eukaryotes having many sites for working out the way from DNA replication is that they are much larger in size than the prokaryotes and also there are multiple functions being performed by them which mostly cover mobility.

Is prokaryotic DNA replication semi discontinuous?

The experiments show that DNA replication is semi discontinuous on the lagging strand while leading has to be continuous.

The process for DNA replication is semi discontinuous as for one among the strands that is synthesized on regular basis and on the other hand another reason is for the formation of the Okazaki fragments which is formed discontinuously.

Semi discontinuous process is the double helix of the DNA that unwinds taking the replication on the 3’ to 5’ stand which gets to process itself easy in the 5’ to 3’. Here the leading strand is worked on continuous and the lagging one is taken for being discontinuous.

The process of replicating DNA in the prokaryotes is semi discontinuous. In some of the microbe, both of the stands can be made to copy on the 5’ to 3’ way together with no need for discontinuous process of replication.

How do you tell if a DNA sequence is prokaryotic or eukaryotic?

The prokaryotic cell do have only one strands of DNA that is circular while eukaryotes have maay linear type DNA.

The gene expression for the prokaryotes do take place in the cytoplasm for there is no definite nucleus and thus the DNA is free in the cytoplasm while the one in eukaryotes take places in the cytoplasm and nucleus.

The DNA that the prokaryotes have is in size small and is circular which is located in the cytoplasm. They are chromosomally arranged and are situated in the cell’s nucleus. The eukaryotic cell is more dense and complex and has organelle having membranes like the nucleus.

Unlike the DNA that is circular in the prokaryotic cells, it in general has only one site for getting the DNA replicated and in the eukaryotes there is a liners DNA in the eukaryotes cell that has many site for the replacing.

FAQs-

What is Replication fork?

The replication fork is formed inside the DNA within its long helical during the process of DNA replication. It is made up of helicases.

This helps in breaking of the hydrogen bonds that holds the stands of the DNA together inside the helix itself. The structure formed as a outcome has two of the prongs branched with each made up of the DNA that is single strand.

Do eukaryotes also have single replication site?

The chromosomes for the eukaryotes have multiple origin sites while just prokaryotes have only one.

This is so as the eukaryotic chromosome are bigger and having multiple origins saves them time. The eukaryotes stores the DNA in chromosomes of nucleus.

Without having many replication sites, the process for replication would take long; it would slow down the cell growth part and also cause degradation of quite few cells.

What is complementary strand?

They are either of the any two chains that do catch up with the double helix of the DNA with regards to the two chains that have been made from the complementary base pairs.

The holophytic species are usually in common referred to as photoautotrophic. They are known to derive their energy for synthesis of food from the sun source. They are also able to use carbon dioxide as the basic source if the carbon.

The autotrophic bacteria are the simple prokaryotes that shall get their carbon needs by getting the inorganic sources biosynthesized. They are the part if the dominant species that are involved in the natural cycling matter.

Photosynthetic autotrophic bacteria examples

The photoautotrophs are for sure capable of getting their own food synthesized from all the inorganic substances.

The photoautotrophic bacteria are the one that are capable of making the use of sun light to. Some of the photoautotrophic bacteria examples are the purple sulphur, green sulphur, purple non sulphur and more.

There is a photosynthetic pigment which is called the bacteriochlorophyll that is just like the chlorophylls in the plants. These bacteria use up the rays of sun to generate energy.

Euglena

These are the genus under for single cell eukaryotes with flagella. They are quite widely known.

Euglena is one among the good photoautotrophic bacteria examples that are widely studied from the class Euglenoidea. This is quite of a diverse group and has 54 general into them.

There is a minimum of 800 species and its species are mostly found in salt water or the fresh water. These are mostly abundant in the inlands that help them to bloom in good summers to cover the water surface in red or green. The species of Euglena gracilis has been used much in laboratory.

Mostly the species here have the chloroplasts that are photosynthesizing inside the cell body that enables them for autotrophy just like plants. They can also complete there nourishment heterotrophically like the animals. Thus they have features for both plants and animals.

They were the first ones to be seen under microscope and the sample for it was collected from the lake that was green in the center and white otherwise.

Due to Euglena having both the features of animal and plants, it was difficult for the taxonomists to get into its classification and thus was kept in unclassified. They reproduce via the mode of binary fission beginning with mitosis and then getting itself into cell division.

Algae

These are said to be the group for the basic aquatics that has nucleus and are photosynthetic along with lacking of roots.

They also lack stems, leaves and many other special functional multicellular structures for the purpose of reproduction that are in plants. Algae are sometimes regarded to be protists and sometimes plants.

Most of the algae are seem to be harmless and are also considered vital for the ecosystem. There are some of its kinds that do release toxins and thus can be harmful to both plants and animals. The place where the harmful algae grow fast and collect in the aquatic place is called harmful algae bloom.

Algae are mostly classified to be green in colour but still are also found in my other variety of hues. The colour of the algae depends on its type and in also some of the cases the way they ought to grow. Seaweeds are also a type of algae.

Some of the much known types of fishes like the Tangs and the Blennies along with the snails, the sea urchins and the crabs to consume the algae. They are also known to eat the red slime algae, the hair ones, the diatoms, microalgae.

Higher plants

They usually are given the names for and plants or the embryophyta and certainly are the good photoautotrophic bacteria example.

The higher plants are the most general types of vegetation on the planet that covers the green on Earth. They are just not concerned with plants but also have a clan that has green algae.

The very term higher plants can be used for all the plants that are said to be planted. It shall include the trees, the herbs that flowers, the fern and its relatives, the tress and the shrubs.

The embryophytes are said to be the land plants for they live mostly in the terrestrial parts while the green algae are generally aquatic. They do are complex being the multicellular eukaryotes and have special organs for reproduction.

There is an absolute difference between plants and algae which is indicated to the composition of cell. Algae can be said to be multicellular and unicellular species while the plants can be only unicellular. Another difference spotted can be that plants do have the vascular anatomies but algae do not.

There can be many similarities between the two of them. Both of them have chlorophyll a and b and the similar carotenoids with algae having many more on addition to it for itself. Both of them store carbohydrates in the form of starch and both are special water plants.

Bacteria

Bacteria are usually the organism that are single cell and are microscopic existing in millions of forms in all environments.

The place for bacterial survival can be both in and outside of the organisms. Some bacteria can be useful, some harmful but mostly serve good.

They do also support many other life forms being both animal and plants and serve their use for the purpose in the field of medicine and industry. They are absolute photoautotrophic bacteria examples for they form a great domain among the prokaryotes.

They are not great in size but just few of the micrometers in the length but are believed to be one among all the first life shapes that did appear on the planet and are also placed in many habitats. These are the creatures that are dominant and have been there for three quarters on the Earth.

They are the ones to have no membrane closed nucleus and all other structures within and are thus said to among the unicellular life forms called the prokaryotes. They do display a lot of metabolism and use just organic compounds as food intake.

Some of the bacteria are the symbionts of the invertebrates and the plants that carry vital host functions like degradation of cellulose and the fixation of nitrogen. If bacteria were nil, there will be no fertile soul and the decay process would be a stop or slow.

FAPs (Filamentous anoxygenic phototrophs)

These are the certain range of phototrophs that have evolutionary significance. They are said to ideal for hot springs.

The best common example for this kind is the thermophiles Chloroflexus aurantiacus. For a photoautotroph to be anoxygenic means to be involved in no production of oxygen.

The reason for its diving into the best fit for hot springs is that it forms a deep classification in the eubacteria descendants and also has a good combination of the elements found in other several and diverse group of prokaryotes that are phototrophic.

The Filamentous anoxygenic phototrophs are quite colorful and are shaped with the cyanobacteria. These do differ from the phototrophs phylogenetically, the group is called as chimeric. The core complex for photochemical reaction for it is same to that of the one in the green sulfur bacteria.

They are also called to be the phototrophic microbial mats that have biofilm in many layers including the phototrophic and the chemotrophic bacteria that make it illuminated and for which they are said to be undisturbed species in the shallow sea or the hot springs.

FAQs

What is binary fission?

It is a mode of asexual reproduction that involves one body separation into two new ones. It also includes duplication of genetics via cytokinesis. 

What are protists?

There are the groups or general category that are quite not related to the other divisions based on that of plants, bacteria, animals , fungi or the Achaeans.

Is a mushroom a Photoautotroph?

Mushrooms are generally the heterotrophs. These are the ones that are not capable to carry on photosynthesis.

Mushrooms are not actual plants but are the type of fungus that has a form of a plant along with a cap and a stem with also a cell wall. They can be said to be a fruits or a flower of the mushroom.

Photoautotrophs are the one that make their food by using light and carbon dioxide to go through the whole process of photosynthesis. They are never confides with the photo heterotrophs that take up only light but not carbon as organic source.

The fruit or flower of the fungus is also a part of its reproduction that helps in getting the spores dispersed. So just like the animals, fungus can also be chemoheterotrophic while breaking the organic stage from the soil to make up chemical energy.

Does Bacteria Have Vacuole: Detailed Insights and Facts

bac 1

Any vacuole is a cell organelle which is bounded by a membrane. They are found in both animal and plants and also it many other species present.

The crisp answer to does bacteria have vacuole will be a yes. It is too typical of the cells of bacteria to have vacuoles. The vacuoles here have water that has particles in them.

Bacteria are the organism which are single celled and are microscopic and are found in million in number both out an inside an organism. Some of the bacteria can be harmful while some do serve to be useful. They are called to support many life forms.

A vacuole is any structure presents in the plant, fungi, bacteria, protists and the animals. They are called to be the largest cell organelles and are shaped like the big sac. The vacuoles are of simple form enclosed by a thin membrane and have fluids in them.

The few of the bacteria and the fungal cells have vacuoles that shall function on the wide storage range for keeping the water balanced and the ions. The formation of the vacuoles in these are dependent on the ability of the bacteria.

How many vacuoles are in a bacterial cell?

The living cells are classified under eukaryotes and prokaryotes. Bacteria are under the prokaryotes.

The bacteria which are commonly called as the cyanobacteria do have gas vacuoles. The cyanobacteria is also called the blue green algae and lives in water.

The cyanobacteria make their own food and are known for it. They do it via the process of photosynthesis and using up the energy from the sun. There are many studies that show that the gas vesicles deflate and inflate along with the light.

The gas vacuoles are the compounds that are contained with a number of gas vesicles. These vesicles are actually long and do tend to be in a parallel alignment and in form of bundles. In the halo bacterium and the purple sulphur bacteria, they are short and are not specifically distributed inside the cell.

The plant cells have large vacuoles but with the question for does bacteria have vacuole, the bacterial cells lacks one compared to both the animal and plants. Not all bacteria have vacuoles but some of them do have it. Some of the examples shall include the blue green algae, halo bacteria, green bacteria and purple sulfur bacteria.

Does bacteria have vacuoles that are large?

The bacteria cells do have vacuoles. In the plants the vacuoles are much larger than in the animals for they suffice different usage.

While not all bacterial types have vacuoles, they are mostly for the purpose for storage, The vacuoles in some bacteria are large and can take up more space than some take up in the plant that is 98% of the area for cell.

Just like the cyanobacteria is approx. 0.5 to 60 micrometers in its length and yet represents a good variety example for bacteria. Thus the bacteria have gas vacuoles with no specific size.

There are many characteristics that differ in the eukaryotes and the prokaryotes. There is the presence of membrane guarded organelles in the eukaryotes but the prokaryotes lack it. There are bacteria available in the planktonic form which grow free in water and have gas vacuoles.

The gas vacuoles in the bacteria are actually filled with air and are shaped for compartments that are cylindrical. They are mainly for the process of buoyancy. The gas vacuoles are mostly found in the bacteria that are marines like the blue green or the halophiles.

Does bacteria have a food vacuole?

Some of the bacteria and the fungal cells do have vacuoles. They are used for the purpose if balancing water and store various ions range.

The vacuoles are made by combining of many small vesicles. Food vacuoles are thus seen in the cells of protists, the fungi, animals and the plants.  The circular regions of the plasma membrane are the food vacuoles.

They are formed to trap or capture the food bits while the particles are entering the cell. When any of the food material enters the food vacuole the vacuoles starts digesting it and then stores is as an energy form.

The vacuoles in bacteria are not common to all but few of them present. In the prokaryotes the ribosomes are made of 30s and 50s subunits and many internal guarded organelles like the vacuoles, mitochondria, the lysosomes, Golgi apparatus are absent.

Do bacteria have contractile vacuoles?

Not every species that has contractile vacuoles are from the fresh waters. Some can be a soil inhabit, some marines and the rest can also be parasites.

Contractile vacuoles are seen in the eukaryotes that get the waste stuffs excreted out of them by the help if contractile vacuoles which is an osmoregulatory structure. Thus, bacteria do not have it.

The contractile vacuoles are very much prominent in the ones that do not have any cell wall. It also comes up with exceptions just like the Chlamydomonas that has a cell wall. It is concerned with osmoregulation.

Some of the species that do contain the contractile vacuoles are a few varieties of algae, the paramecium and the amoeba. There are few sponges like the choanocytes, the pinacocytes and the amoebocytes and the hydra along with the single cell fungi also have these.

These vacuoles are the concerned organelles types that’s hall contract and expand getting to regulate the level of water out and internal of the cell. The contractile vacuoles also help the cell absorb less amount of water.

Contractile vacuolesWikipedia

What cells are vacuoles not found in?

Vacuoles are the organelles which are found in both animals and in plants. They are also seen in other organism like the fungi, protists and bacteria.

Not do all cells have vacuoles. The plants have only one vacuole large in size whereas the animals have vacuoles in them that are small.

The vacuoles in animal are tiny in capacity on getting to compare with the plants. The presence of vacuoles is good in fungi, protists and some animals and plants. The vacuoles in subjected to perform different in various cells.

If the plants had an absence of vacuoles, they shall not be capable of carrying out the normal function and thus shall eventually die. The vacuoles are important in plants which help in maintaining the structure and helps in storing water.

Inside the animal cells, the vacuole is small compared to that of plant but there are the presences of many number of vacuole that are sued for several functions. They help in getting the cell protected, isolates the waste products, helps in balancing the hydrostatic pressure and more.

If the animals lack a vacuole they shall starve to death and won’t be able to store any of the nutrients needed for the well-functioning of the cell leading it to die without a vacuole.

Do bacterial cells have a permanent vacuole?

The bacteria are all single cell. They are also called the prokaryotes and are not supposed to have any nucleus or any other structure having a boundary.

The permanent types of vacuoles are found in the fungal cells and the plants cells. An example can be the xylem that attaches its vacuoles together to create the xylem. The permanent are always devoid of regeneration.

The permanent vacuoles are filled up with the cell sap that helps them keep the cell in turgid state. The prokaryotes generally do have genetic material but are not enclosed inside a membrane. They have circular DNA and are inside the cytoplasm.

The vacuoles are important in animals but are not as permanent like the plants. They are used up for the storage purpose  in most cases which shall be differing from nutrients, the needed proteins or any other harmful substances.

Do bacteria have vacuoles in all?

The vacuoles are structured to be found in animals, plants, the fungi, some of the protists and bacteria.

To the question for do bacteria have vacuoles, the answer is a yes. But, for all bacteria having vacuoles is a no. The typical bacteria cells do have vacuoles.

The vacuoles in bacteria are used for keeping water and have organic and inorganic molecules. Some bacteria like the cyanobacteria pr the blue green algae, the halo bacteria, the purple sulfur bacteria and the green bacteria do have vacuoles.

The main purpose of a vacuole in bacteria is to have a use in storage of various ions and help in water balancing inside the cells. With not all of them having vacuoles, the ones that have are used for the purpose of storage.

FAQs-

Why do plants have larger vacuole?

Vacuoles are the organelles that are found in plants, animals, the fungi, the bacteria and also few protists.

The plants have larger central vacuole and are greater than animals for they need to store water and foods. As the plants can’t move like the animals they need larger reservoir.

What are the types of vacuoles?

Any vacuoles are the membrane covered organelles and are of four types commonly the sap vacuoles, gas vacuole, food vacuole and the contractile vacuoles. All have different cells to perform.

What are basic function vacuoles?

The functions of vacuoles depend on the type of cell and the place of its location.

In animals they are small and are for saving the waste materials. In plants they are used for water balance taking up the entire space of the plant cells.

A very simple definition for the word vacuole is that it is a space which is devoid of cytoplasm, bounded with a membrane and has fluid.

With the question for Do animal cells have vacuoles, the answer is yes. Animals do have vacuole but are small in size when compared to plant cell. The probable function of vacuoles can be said to be a modern form of lysosomes.

Vacuoles are organelles having membrane found in both animals and plants. Humans also have vacuoles. These organelles also have a common generic term which means a membrane enclosed organelle and is like the lysosome. The reason for this is that the function of vacuole is just to take care of the waste products and handle them by getting rid of it. 

On getting to compare the vacuole of animal cell with the rest or plants, the size of its vacuole is smaller for they do not need to store much of anything like water, or inorganic and organic materials for cell functioning.

Do Animal Cells Have Vacuoles
Animal CellsWikipedia

Do animal cells have vacuoles in all?

Vacuole being a organelles with membrane is very much common to plants, fungi, animals and protista.

Animals’ cell do not necessarily have a vacuole always and never have a large sized vacuole for it would lead to harming of the cell and then interfere with the functioning of cell. Thus they use up small vacuoles varying in number.

The vacuoles in the animal cell are tiny when compared to the counterparts of plants but are also more in number than any other possessed organism. There are many animal cells that do not have vacuole.

They are basically the storage bubble in the cells. Inside the animal cells, they mostly perform subordinate roles like helping in the process of endocytosis and exocytosis. Despite the animal cell having vacuole small in size than the plats, they are more in number compared to the cell of plant and are scattered all over in the inside of the cell.

The cells of animal do not have a central vacuole which is large in size as noticed in plants. But, the animal cells, mostly the fat cells do have vacuoles with membranes for waste, storage of materials.

An example of a vacuole in an animal cell is lysosome. They are also membrane having organelles that have digestive enzymes in them. They are used for breaking down of extra cell parts and destroy any harmful bacteria.

Vacuole- Wikipedia

Where are the vacuoles in an animal cell?

Any vacuole is a membrane bound space which is located inside the cytoplasmic space inside the cell.

The membrane that surrounds the vacuole is called as tonoplast. The components or the interior of the vacuole are called as cell sap and is different from the nearby cytoplasm. The membrane of the vacuoles is made up of phospholipids.

The membranes are also composed of proteins that shall help in the transport of molecules just across the membranes. There are vacuoles in composition that help the vacuoles to keep themselves intact and hold onto several materials.

The vacuoles are the bubbles in the cell used up for the purpose of storing. They are in larger size in the plants whereas are in large number in animal. Vacuoles are designed to store water, food or any type of nutrients that a cell shall need to survive.

There are many number of vacuoles in animal cells with being located in different places and thus are given different names. Plants have only one large vacuole.

What are vacuoles in animal cells called?

The vacuoles and its contents are kept separate from the cytoplasm and are thus referred to by many people as ergastic.

The filling of the fluid inside the vacuoles is called the cell sap which is surrounded by single membrane sac called tonoplast.

These vacuoles help in-

Storage

A vacuole uses up the space to store minerals, the proteins, salts and the pigments in the cell. There are many lipids that are stored inside the vacuoles as well.

The solution that helps in filling of the vacuole is called as a cell sap. It is also filled up with protons distancing from cytosol and helps in balancing the surrounding acidic ph.

Turgor pressure

The vacuoles are to the top level filled up with water and thus exert a great force on the walls of the cell.

This forces exerted is called as turgor pressure. It also provides cell shape and helps the cell stand strong during any harsh condition.

Endocytosis and Exocytosis

The substances inside the cell are taken in via endocytosis and taken out by exocytosis.

The substances are kept in cell and are separated from the cytosol. This proves of endocytosis varies from cell to cell with regards to intake of food and digestion.

Do prokaryotic cells have vacuoles?

Eukaryotic cells do have many organelles that are membrane bound like the nucleus but the prokaryotes lack it.

Animal cell do have a vacuole but are small and scattered all over. Thus the prokaryotes use it to store or have materials transferred. There is also a presence of gas vacuoles in prokaryotes.

The gas vesicles are the free nanocompartments which stretch gas and are mostly found in Cyanobacteria and also seen in other species of bacteria and some other archae.

The plant cell also has a permanent vacuole called the central large vacuole which is filled with cell sap and helps the cell to push the contents of it against the cell wall and then keep them turgid.

Vacuoles are said to the organelles which are found in both plants and animals which make the prokaryotic part. They are specified in their own way and perform task according to the location.

How many vacuoles are in an animal cell?

With taking the question of Do Animal cell have vacuoles, the answer being yes, there is a lot of consideration on this part.

Animal cell having vacuoles are much small in size but more in number than compared to the rest of the species having a vacuole. Animals have vacuole scattered all over. The plants have only one vacuole which is large in size.

The vacuole is centrally placed used for the purpose of storing water, balancing the cell pressure and the hydrostatic one. On the other hand, animal cell have the vacuoles in minute sizes but varies in different location. The function of any vacuole in the animal cell varies according to the location they serve for.

Some of the type of vacuoles found are-

Gas vacuoles- They are found in cyanobacteria and are free to gas transfer. They help the bacteria in controlling their buoyancy and formed while the small structures grown to form the species.

Contractile vacuoles- They are for osmoregulation and are special organelles that are found in the free surviving protists, it is the part of the contractile process that helps in removing of waste and ions to keep the water balance intact.

Food vacuole- They are also called the digestive vacuoles and are found in the organelles of the animals like Ciliates, the plasmodium falciparum, the protozoa and the one causing malaria.

One vacuole not found in animal is-

Central vacuoles- Animal do not have any central vacuole nut plant do possess which cover 90% of the cell volume in them.

Why are vacuoles different in plant and animal cells?

Vacuoles are the organelles needed by both animal and plants. They are both membrane bound and are present within the cell.

The main separation point for the animal and plant vacuoles is that the plants have a vacuole which is greater in size and is just one in number while the animal has many vacuoles and are tiny in their size.

The plant having the facility of a centrally placed large vacuole serves in the process of storage of material and also for transport of items and considering the waste material.

The stability given by gathering the cell wall and the turgor force being mechanical lets the cell of the plant grow to much greater size so that they can take much more space or volume than the animal.

The animal cells having their vacuoles small as they do not need much of their space to store in water or any materials like that of any other organism or the plants. They are scattered else places and function on their own.

FAQs-

Do all animal cells have vacuoles?

No, all animal cell do not possess vacuole. There are few of the cells lacking the presence of it.

Do animals have a central vacuole?

Animal cells have many numbers of vacuole but small in size. Plants have a central large vacuole.

Why does plant have large vacuole?

The plant cells have large vacuole for they need to store up water, the inorganic and organic components for the proper working of cells.

What are lysosomes?

Lysosomes are organelles that help in macromolecules to be broken down for digestion and also get its response against any foreign materials entering the body.

They are also called as suicidal bags as they have digestive enzymes and in case of there is a burst, it release digestive enzymes that releases all the cells leading to the cell death.

Eukaryotes are any organism which contains a definite and clear nucleus. The cell of eukaryotes has a clear nuclear membrane.

Very common example of eukaryotic cell are the-

These have well developed nucleus and organelles. Still, there are exceptions and the Monocercomonoides lack mitochondria and nucleus in the red blood cell.

The nuclear membrane of the nucleus surrounds it and consists of well-developed chromosomes which are the hereditary materials. All the example of eukaryotic cell consists of organelles.

These organelles includes mitochondria which is the energy cell, the Golgi apparatus which is a secretory device , an endoplasmic reticulum which is a canal like membrane system inside the cell and the last is lysosomes which are the suicidal bag.

Features of Eukaryotic cell

They very basic feature of the eukaryotes is the presence of an inside membrane that separates the DNA from the remaining of the cytoplasm.

The DNA in the eukaryotes is in general organized in more or only one long chain which is called the chromosomes.

The eukaryotes also have many other membranes within it which form many distinct surrounding that are subcellular. Each of the internal subcellular compartments is called organelles.

The organelles are able to get an optimum temperature for any definite process. This indicates that the eukaryotes are in general much more versatile and efficient than rest of the prokaryotes.

Single cell life

The entire organism that anyone is familiar with can be referred to as an example of eukaryotic cell.

The single celled organism consist of bacteria many other types of fungi and algae, the amoeba, the paramecia and the slime molds. The single cell has two units for its division.

The two units areone with no organelles and other with no nucleus. The two kingdoms are the eubacteria and archaebacteria. The kingdom of Protista has the most number of single celled and Fungi have both multi and single celled.

The entire organism which is single celled like the amoebae, paramecia and the yeast are all eukaryotes. Stating from the pine trees to that of the potatoes and limiting to grass all are classified to be eukaryotes.

Some of the common examples are flies, moles, tapeworms, algae, fruit flies and mushrooms.

Few common example of eukaryotic cell

Animal cell

The animal cell includes many various types of organelles that help them vary out specific functions.

Just like bacteria, the animal cell also has plasma membrane, DNA and cytoplasm. One might get to notice that the external and internal of the animal cell; looks a bit different from the one of bacteria.

All the animals ranging from fish, whales, cats, humans, arthropods including the domestic animals belong to the group for example of eukaryotes cell and its types.

In the terms of science, animals are often referred to as metazoans or the group members if the Kingdom Animalia. For more than all, this is the most common group of eukaryotes.

The animals have cell that have cell membranes but have no cell wall that is rigid just like the fungi, plants and some other protists. On considering them as a group they are much flexible, more mobile, and active part of the eukaryotic group with an exception of the coral that are present.

For the one in animal cell, they do not have any cell wall. To cover this up they have a cytoskeleton which is regarded as a network of filaments that gives support and helps in internal cell to cell transport.

On addition to it, many of the animal cell do have a nucleus and a special type of organelles which has the DNA stored. The DNA within the nucleus is the one which is generally organized inside the strings and is called as chromosomes.

The cytoplasm is the example of eukaryotic cell is filled up with various types of organelles which help the cells grow, live and then reproduce. These are many organelles that dwell in cytoplasm with the functions.

Golgi apparatus- they are used to modify, pack and sort all the proteins inside the transfer vesicles so that they can reach anywhere in the cell and can be secreted.

Vesicles- They are the tiny membranous sacs that helps the material gets transported inside the cell and can fuse with the membrane of cell to get the contents released.

Smooth endoplasmic reticulum– These help in getting them separated from the nuclear membrane but then are in alignment with the rough endoplasmic reticulum. They do not have ribosomes and are in the site of lipid synthesis. They help in detoxification and help in in transportation of cell material.

Rough endoplasmic reticulum– they are continuous inside the outer layer of the nuclear envelope and include the embedded ribosomes on the external membrane. They help the cell in material transport and then segregate the protein newly made for the purpose of its transport by vesicles.

Ribosomes- They are indulged in synthesizing of proteins.

Mitochondria– this helps in generating of energy and converts adenosine diphosphate to adenosine triphsophate. This is also considered to be power house of the cell.

Centrosome– The materials of the pericentriolar and the centrioles within do play an important role for cell division and in building up of the microtubules.

Lysosomes- This also includes the peroxisomes and helps in getting rid of the waste with breaking down of the compounds and then getting the cell structured recycled.

Plant cell

They carry out the process of photosynthesis by the use of the organelles called chloroplast and do have cell wall.

Just mostly like the rest of the example of eukaryotic cell, plant cells also has there nucleus and stored their DNA within it. They are different from animals and many ways.

The very basic difference is that unlike the animal cells, the plant cells have a cell wall and are also much different from the one of the prokaryotic cells.

There are about 250,000 plant species ranging from the very mosses being simple to the eukaryotes being complex and also the hard flowering plants. The plant make more oxygen than they utilize from earth. 

The plant cell do have channels which are known as plasmodesmata which helps the cell to communicate from one cell to other by transporting ions, proteins, sugars and RNA.

The plant cells have cell walls which bear cellulose and also chloroplast. Plants use up chloroplast to turn up sunlight into fuel and then produce oxygen to be used up by the cell.

Both the animal and plant cells do possess mitochondria. This organelle uses up oxygen and glucose to get carried out with the process of creating of TP and respiration. ATP is a molecule which powers plant cell process.

On addition of the plant cell having mitochondria they also have chloroplast which are vital for the process of photosynthesis. In the process of photosynthesis, the plants uses up water, sun rays and carbon dioxide to make glucose.

This glucose is later on broken down with the help of a process called cellular respiration. Both chloroplast and mitochondria have their own separate DNA which is differentiated and distinct from the DNA possessed by the nucleus.

There is also a presence of another structure in plant cell but not in animal and is called the central vacuole. Inside the plant cells, the work of the central vacuole is to maintain the turgor pressure by having kept the large vacuole inside contained with water that shall help support the cell.

They are the single celled eukaryotes and a good example of eukaryotic cell. On considering all the biology rules, there are exception too.

There are many types of seaweed which are tagged with the name of being protists despite having many cells. The protists contain quite a variety of organism.

Very few or some are not much related to each other. According to genetic research, there are reveals that say that protists have a minimum of ten groups similar to the other kingdoms.

To get a perspective of this, all the animals ranging from the worms to the humans, have been put in one kingdom. Some examples of eukaryotic cell protists consist of paramecium, amoeba, kelp and more.

Fungi

This example of eukaryotic cell is not similar to the rest. They can have many cells or exist in one. The scientists have once believed that the fungi were categorized to be a plant.

Moreover, considering the cell level they have quite a feature common to hat of the animals and plants. The first can be the cell wall is made of a protein called the chitin which is same as that of in the animal beetles but not plants.

The microscopic examples include the yeast that are used up to make wine, cheese and beer. The inclusions are also the organism that can cause ringworm and athlete foot. Much macroscopic examples can also include truffles and mushrooms.

Some parts of the eukaryotic cells are-

  • Cytoplasmic reticulum– Also referred to as the cell membrane. It is semi permeable and separates all the within of the cell from the outside. They contain carbohydrates, phospholipids of two layers and proteins. The structure of the phospholipid is defined in the Fluid Mosaic model.  It helps the cell keep away from the cell and all injuries and helps in transport of molecules across membranes.
  • Cell wall- It is a non-living structure and is rigid located outside the plasma membrane inside the fungi and the plant cells. It is absent in the animal eukaryotic cell. Different eukaryotes have different composition of the cell wall. Some of the objects in plats are pectin, hemicellulose, and cellulose. In fungi, it is mannans, calcium carbonate and galactans.
  • Endoplasmic reticulum– They are a chain of tiny tubular leads. The space within the eukaryotic is divided by this and has two parts- the cytoplasm and luminal.  They are basically of two type- smooth and rough endoplasmic reticulum. It is involved in lipid and protein synthesis. The rough reticulum helps in protein folding and transports it to the Golgi apparatus.
  • Nucleus– This is the vital call organelle. It a structure of the soluble membrane with all the genetic information and is referred to as the brain of the cell. The nucleus is seen in almost all the example of eukaryotic cell. These also have an exception and are the sieve plant cells and the human red blood cells.
  • Plastids– They is also the double membrane organelles seen in the plant cells. They include pigmented and are of the types chloroplast that have chlorophyll within them. The other includes leucoplast that are the colorless ones, chromoplasts which are the colour giving pigments.
  • Ribosomes– These are the structures which are not bound by any membrane. They are also called as the protein factories as they are the main site for protein synthesis. They are made up of ribonucleic acids and the proteins. They also synthesize polypeptides.
  • Mitochondria– These are the membrane bound organelles and are referred to as the power house of the cell. There are two membranes which are inner and outer. The inner part is divided into cristae and is semi permeable. Then the membrane divides lumen into outer and inner compartment.
  • Lysosomes– These is located inside the Golgi apparatus and are vesicles with bounded membrane. They are the suicidal bags as they are basic in hydrolytic enzymes like the lipases, proteases and carbohydrates. They have an optimal ph. less than 7 for optimal activation. The main use of this is to let in digest proteins, nucleic acids, carbohydrates and lipids.

Example of Prokaryotic cell: Detailed Insights and Facts

Prokaryote cell.svg 2

Prokaryotes are the unicellular organism which does not have any membrane bounded structures including the basic called nucleus. They do no possess any cellular regions as well.

With the prokaryotic cells lacking almost many organelles, some of the examples of prokaryotic cell are the bacteria, mycoplasma and the blue green algae. Among these, bacteria are the most common ones.

Some more common examples of prokaryotic cells are-

All living being fall into two groups wither eukaryotes or the prokaryotes. The determination of the group of an organism is done based on the cellular structure.

The prokaryotic cells are indeed small and have simple cells that measure around 0.1 to 5 μm in diameter. Inside the prokaryotic cells, the DNA bundles are in stored all together inside a region called as nucleoid.

Cyanobacteria

They are the aquatic and photosynthetic in nature and are most in common form of bacteria. Cyanobacteria resemble bacteria in their structure.

They are the oxygenic phototrophs and example of prokaryotic cell which have in them a green pigment known as the chlorophyll. Along with a green augments they also have a blue one called the phycobilins.

They are also referred to as the blue green algae. They are important in the formation of the oxygen level in the earth’s atmosphere. They also help in several other attributes which are important to human life. They are microscopic and are found in several types of water bodies.

Just like the true algae and true example of prokaryotic cell they lack mitochondria, any membrane based nucleus and organelles. They obtain their own energy directly from the light source and get them converted into chemical for preparing their own food. This process is called photosynthesis.

Archaea

They are the group of cell that is single organism that is example of prokaryotic cell. These define the limits on earth.

Some of the examples of archaebacteria consists of the halophiles which are habitat of the salt surroundings, the methanogens that are the organism that produce methane and the thermophiles that can live in a very hot habitat.

They are organism that does not have a definite nucleus and are quite distant from the molecular characters that separate from the bacteria. Members of this group are Pyrolobus fumarii holding the upper temperature.

They had been discovered in the harsh conditions of nature like In the hot springs and the vents. They have their occurrence in the various ranges being acidic, saline and all the anaerobic situations. 

The major part of archaea cannot be made in labs and the presence in the global areas has already been noticed via the use of many techniques that are culture independent.

Bacillus anthracis

They are the gram positive with being rod shape as an example of prokaryotic cell. they measure about 3 to 5  micron and have circular single DNA.

They cause up anthrax which is known to be a deadly disease for livestock and sometimes to humans as well. It is the only pathogen which is permanent along the Bacillus genus.

The discovery of this was the very first evidence in science for the germ theory of diseases. They are known to have 89 strains. Sterne strain is used in vaccines, vollum is isolated from cow.

Anthrax 836 is a high virulent strain by USSR. Ames strain are also siiolated from the cow and famous for Amerithrax attacks. H9401 is isolated from a Korean human patient using the anthrax vaccine.

It has some capsule which is a need for a full vaccine. It produces mostly there plasmid exotoxins. These can cause many infections and also can be treated with penicillin, ciprofloxacin and doxycycline.

Bacillus careus

They are the gram positive bacteria which are rod shaped and are anaerobic in nature.

These example of prokaryotic cell are motile also beta hemolytic and are known to form spore in the soil, aquatic sponges and food. The name cereus means “waxy” in Latin which means the visibility of colonies build on the blood agar.

These are said to produce toxin and are also said to be found in vegetation. It is said to cause diarrhea, vomiting and nausea. They are also associated with various infections in hosts and also are capable of causing septicemia.

These prokaryotic cells can lead to loss of vision and gastrointestinal illness. It is also associated with production of exo-enzymes that lead to destruction of tissue. They in the surrounding are ubiquitously an form spores allowinh them to survive long in harsh conditions as well.

Bacillus cereus is also caused by ingestion of contaminated food. Similar responses for the problem in respiratory tract have also been noticed in here for these bacteria.

Streptomyces soil bacterium

These are the bacteria from the family of actinomycetes and are the soil bacteria.

They are mostly in common in the family making up to 1 to 20% of the soil microbes that are cultured. The growth if its colony becomes more visible when there is a germination of spore and producing of filaments having many nuclei.

The filament of these bacteria elongates by the apical growth and branch out by continuous producing of mycelium that generated from both culture medium and inside it. There is also a formation of hyphae formed by the mycelium.

An approx. of all the natural antibiotics, two third of them and about almost 75% are from the Streptomyces genus. It has been sensed by Berdy that these generate about 7600 compounds that are bioactive in nature.

Most of these bacteria are either rhizoplane or rhizosphere colonizers. They can also be said to be endophytes that help colonize the within tissues of any host plants. These features of the example of prokaryotic cell make them a farmer favorite.

These hyphae penetrate from the medium in the visibility of the extracellular hydrolytic enzymes that mixes up the organic molecules that are present. They have filaments that allow them use the nutrients up to their efficiency and also enables colonization.

Escherichia coli bacteria

They are in general known as E.coli and are gram negative bacteria. They are the facultative anaerobic and are rod shaped.

Mostly these stains of prokaryotic cells are harmless and found mostly in the low intestine of all the warm blooded creatures.  Some of the serotypes still can be the cause for food poisoning in the hosts.

They do play role in getting the food contaminated which prompt recalling of the product. The one that are not dangerous are part of all day microbut in the gut and benefits the host by generating of potassium.

These types are excelled out in the surrounding in the form of fecal matter. They grow mostly in fecal matter which are fresh under the aerobic conditions for about three days and decline slowly after the process.

Streotpcoccus bacteria

They are the compositions of the gram positive type of bacteria and are general example of prokaryotic cell.

The cell divisions in the streptococci takes place in the singular axis as they grow. They do tend to grow from chains or pairs that lead to getting it twisted. It is quite different from Staphylococci.

Thus for the reason they do not have a specific shape and form mostly clusters looking like grapes. Most of these are catalase negative and is oxidase negative with many also being factitive anaerobes.

They are of firmicutes phylum, class being bacilli. They are of order lactobacillales and the genus refers to streptococcus. They are also responsible or many cases like the bacterial pneumonia, pink eye, the endocarditis and endocarditis.

Moreover, mostly all the species are not pathogenic and thus form a part of human commensal microbiota in the skin, intestine and mouth. They are also an essential in generation of Emmentaler.

Lactobacillus acidophilus

The lactobacillus acodophilus are the ones which are located in the intestine. They do produce lactic acid and are thus given its name.

They are the members of genre Lacto bacillus and so play a role in human health. This is done by generating an enzyme known as lactase. They balance their way of being good and bad.

They help in balancing out quote of the harmful bacteria that shall not else flourish inside the gut for any antibiotic or illness. They are also used in getting the flora of that vagina balance and also prevent any generation of any infection.

They are mostly found in yogurt and many of the fermented food with also being and preferred in the form of supplement. They are mostly found in the non-pathogenesis organism and few of the strains are made in use as probiotics to get oneself prevention of some diseases.

Streptococcus pyogenes

They can be also termed as group A streptococcus (GAS) and are facultative gram positive bacteria that occur in chains.

They are also said to cause many more infections in the humans that consists of tonsillitis, scarlet fever, rheumatic fever, cellulitis, necrotizing fasciitis and pharyngitis.

They also can many diseases that can be life threatening just like bacteremia, myonecrosis, pneumonia and streptococcal toxic shock syndrome.

They are also a global vital human pathogen that helps in causing a large variety of infections that are acute in nature like the pharyngitis and many other infections in the soft tissue.

They can spread via any direct contact with nose discharge and throat. Sometimes they also spread via any infected and exposed wounds or via any sores on skin. The risk of it is high while a person is ill or has an infected wound.

Sulfolobus acidocaldarius archaebacterium

Sulfolobus are the genre of microbes which form in the family of Sulfolobaceae. It belongs to the domain of archaea.

Sulfolobus species do grow in the volcanic springs with an optimal temperature of 75 to 80 degree Celsius and a ph. level of 2 and 3. It helps making them thermophiles and acidophilus in general.

 They are found in mostly in the Yellowstone national park’s that is rich in sulphur. They occur in very high temperature and also in high numbers getting it attached with the surface of any sulphur crystals.

Cell features of Prokaryotes

Some of the possession for the example of prokaryotic cell are-

  • Ribosome- They is used during the process of protein synthesis.
  • Nucleoid- It has the DNA and is the central area of the cell
  • Cell membrane– All prokaryotes have a cell membrane which is also called the plasma membrane. They help the cell separate themselves from the outside world.
  • Cytoplasm- they are the semi fluid inside the plasma membrane. The cell of the prokaryotes lack membrane covered organelles; they do contain some important features.
  • Mesosomes– They are the extensions of plasma in the cell that from the tubules or the lamella.
  • Glycocalyx– They are also called the slime layer and are mad eup of macromolecules and can be thick or loose.
  • Cell wall- Just for the outside world, cell wall helps give protection and maintains the structure. Mostly all examples of prokaryotic cell have a cell wall that is rigid which is made of proteins known as the peptidoglycans and carbohydrates. 
  • Capsule- There are some bacteria that have in them a layer of carbohydrates which envelop the wall of cell and are called the capsule. This capsule helps the bacteria keep themselves attached with the surface.
  • Fimbriae– they are the thin like structure also are same like hair which are used by the bacteria with their cellular attachment.
  • Flagella– they are the tail like similar thin structures which help the organism in their movement. It has three parts, the filament, hook and the basal body.
  • Pili- It is the rod shaped bodies which are involved in many roles that also incudes the transfer of DNA and cell attachment.

Purple Sulphur Bacteria Examples: Detailed Facts

alp

Purple sulphur bacteria are the classification of the Proteobacteria type of the bacteria that are potential for photosynthesis.

Some of the purple sulphur bacteria examples are Spiribacter salinus, Chromatiaceae, Spiribacter roseus, Aquisalimonas halpphila, Aquisalimonas lutea, Spiribacter aquacticus, Spiribacter curvatus and Arhodomonas.

The purple bacteria examples are divided into three classes-

Alphaproteobacteria

The members of this group are diverse and have many in common yet nevertheless also share common ancestor. Just like the rest of the proteobacteria, they are by nature gram negative.

There are very few studies that actually refer to the genetic natural transformation in the few examples of alphaprobacteria and thus the process identified has been named and seen in Agrobacterium tumefaciens, Bradyrhizobium japonicum and the Methylobacterium organophilum.

Some of its own intracellular parasitic inclusions lack the peptidoglycan and are also in general gram variable. As a whole, the class includes protomitochondrion.

AlphaproteobacteriaWikipedia

Betaproteobacteria

This class comprises of 400 different species in bacteria and 75 genera in them. In all, the Betaproteobacteria shows a good classification of all the metabolic process and occupies various environment from pathogen lying inside the host organism to the oligptrophic ecosystem.

Most of the Betaproteobacteria are heteroptrophic that derive the electrons and the carbon from the organocarbon sources. Some of them are photoheterotrophic deriving energy from carbon and light from all the organocarbon sources.

Rest are autotrophic that derive their carbon from all the bicarbonate and carbon dioxide with their electrons from the reduced inorganic ions like sulfhide, ammonium and nitrite with many also being chemolithoautotrophic.

Betaproteobacteria are mostly used as nitrate with being the electron acceptor and also can be used remove industrial waste by denitrification.

Betaproteobacteria – Wikipedia

Gammaproteobacteria

This group contains 250 genera, that make it most rich in taxon and genera for the prokaryotes. It is quite in parallel with use in medical, ecological and important scientific groups.

It is made up of the all the gram negative microbes and is mostly physiological and phylogenetic diverse class in the Proteobacteria. They can mostly live in marine, terrestrial and play important roles that include the extreme surroundings like the hydrothermal vents.

The purple sulphur bacteria examples are the gram negative type that produce their own food via the process of photosynthesis and thus are phototrophic. They are high in pigment with the bacteriochlorophyll A and B along with several other carotenoids.

These shall be divided into two further groups- the purple non-sulphur and the purple sulphur. The purple bacteria are regarded to be anoxygenec phototrophs that are found in wide range in the nature but more are aquatic with anoxic state favoring pigment synthesis.

Where are the purple sulfur bacteria found?

The purple sulfur bacteria are usually found within the illuminated zones of the water or lakes regions that are anoxic.

These are the area where there is an accumulation of hydrogen sulphide or also in the sulfur springs where there is a production of hydrogen sulphide via biological process or geochemical. This triggers the formation of purple sulfur bacteria blooms.

The purple sulphur bacteria examples are mostly species that thrive in the soil, the rivers, mud area, moist, lakes, ponds, marine places and the sulphur spring. The green and purple bacteria are mostly and often seen in the region of mud, river and lakes

How do bacteria use sulfur?

Sulfur is an important to all organisms. It takes up sulfate from sea water, soil, algae and plant. It is used up to make one or more needed amino acids which are also used for protein making.

They are also used as co-enzymes. The sulfur usually produces slime and helps the rest bacteria like iron bacteria to grow. There are certain bacteria which are referred to as sulfur reducing bacteria which are capable of reducing sulfur to hydrogen sulfide.

These microbes use up the compounds of inorganic sulfur as accepting electrons that shall help in sustaining many activities like respiration, growth, stable energy during no presence of oxygen.

The sulfur is stored in the storage globules in bacteria and plays a central use in metabolism of certain anaerobic microorganism. The very prominent among all the rest are the bacteria that oxides sulfide from sulfide to sulfate.

Is purple sulfur bacteria autotrophic?

The autotrophic bacteria are the one that synthesize their own foo. They are seemed to perform certain actions that include the photons or the light sources or energy and the chemicals.

The given purple bacteria examples carry out several functions that help and allow them to get themselves adapted to various and even more conditions in the extreme surrounding. These are thus photoautotrophs and also called as chemoautotrophic and also photoheterotrophic.

This is in order to get the energy for the purpose of sustaining biologically. On considering this state, the make the use of inorganic compounds just like water, carbon dioxide, hydrogen sulfide and much more. 

They are a very strong evidence if photoautotrophs and are widely spread with having a limitation in their capability to photo heterotrophy and also are poor to getting used to with the dark phase of growth and metabolism.

What is the purpose of purple sulfur bacteria?

The purple sulfur bacteria also termed as PSB are photosynthetic and get in work to reduce the carbon dioxide to carbs with suing up of no water.

They use up hydrogen sulfide and not water for easy work. On addition to this and related to growth factor, the purple sulfur bacteria have high concentration of sulfide and ammonia that helps in promoting of the growth.

They are able to contribute to the environment by taking part in the nutrient cycling and with the use of their metabolism to change the nearby. They play a role in primary production that suggests that these are able to affect carbon cycle via fixing carbon.

They also take part in phosphorous cycle and the iron cycle. With upwelling of all these there is a recycling of oxic layer of the ales which is given to the heterotrophic bacteria for the use. They also contribute to the place for the purpose of their growth.

Why does purple sulfur bacterium release elemental Sulphur?

Just like the rest algae, cyanobacteria or the plants, the purple sulfur bacteria are not seemed to use up water as the potential reducing agent and thus are not capable of producing oxygen.

The sulfur is in terms oxidized to make granules of the elemental sulfur which in turn gets to oxidize the formation of sulfuric acid. The sulfur bacteria are commonly in capacity to use up several sulfur compounds that are inorganic.

These elements include sulfite, thiosulfate, the elemental sulfur with in terms are sued up by the purple sulfur bacteria as a source of energy. Nevertheless the final product is always sulfate.

What are purple non Sulphur bacteria?

The purple non sulphur bacteria are commonly referred as PNSB and are phototrophic in nature. This gains lot of increasing attention in the production of plant.

The attention is for their capacity to gather and produced compounds of high value which are useful for their growth of plant. They can fix up carbon dioxide along with nitrogen. They are capable of breaking organic compounds as well. The sources of their energy are mostly the organic and inorganic elements and light. They can be found in dark and glowing areas which have no sulfide. They do no form blooms and thus have no high visible concentration.

What are Carotenoids?

Carotenoids are pigments that are synthesized by the bacteria, algae and plants. They are responsible to offer the bacteria the colour of red, brown, purple and orange.

What is Protomitochondrion?

These are the bacteria that had been engulfed by the entire ancestor being eukaryotic and had given rise of mitochondria which are the organelles inside the eukaryotic cells.

What is Hydrothermal vents?

These are the outcomes of the seawater percolating under via the fissures in the crust of the ocean with the vicinity in the subduction zones.
