Let us discuss these facts to answer are algae phytoplankton.

Which algae are phytoplankton?

As they want mild to photosynthesize, phytoplankton in any surroundings will drift close to the pinnacle of the water, wherein daylight reaches. Mostly, the freshwater algae phytoplanktons are mix of akgae abd cyanobacteria.

It is also called as blue-green algae. The phytoplanktons that are found in mariene places are mainly called as dinoflagellatesa and diatoms. Sometime other algae like cyanobacteria and other are also seen to there.

The dinofagellates contain tail like structure called as flagella while the diatoms do not have flagella but they move with the flow of waves in the ocean or we can say water currents. Some examples of phytoplankton include- Cyanobacteria and silica-encased diatoms. Green algae, dinoflagellates, and chalk-coated coccolithotrophs.

How algae are phytoplankton?

As the name suggests, phytoplankton is a type of algae that needs sunlight to live and is commonly found in marine and terrestrial environments.

They are found in the uppermost layer of sea, oceans and all other marine habitats, and from there they take sunlight to grow and also use the sunlight to prepare their food since they also have chlorophyll.

The most important note is that phytoplankton contain chlorophyll, and  when we compare green algae, we find chlorophyll in them also. They are alage phytoplankton.


In the end, we can say the answer to the question are algae phytoplankton is yes. Some algae are phytoplankton that depends on sunlight and are found in marine areas. This would have clear the question are alage phytoplankton.
