Question

why cyanobacteria is also called blue green algae??

Answer 1

Because they are photosynthetic and aquatic, cyanobacteria are often called"blue-green algae". This name is convenient for talking about organisms in the water that make their own food, but does not reflect any relationship between thecyanobacteria and other organismscalled algae.

Answer 2

Hey dear!!

Here is your answer...

Cyanobacteria appear coloured because they contain the photosynthetic pigments chlorophyll (green) and photocyanin (blue). This means that they can produce their own food.
That's why cyanobacteria is also called blue green algae.
