The ends of the cell are usually tapered and may be pointed or rounded. The nucleus is located in the center of the cell between the chloroplasts.
What is the difference between diatoms and Desmids?
– Diatoms are stramenopile algae, their cell wall is composed of silica and their chloroplasts are yellowish- brown. Desmids are a group of green algae in which their cell wall is composed of cellulose and pectins (like that of plants) , and their chloroplasts are green.

Why is BGA called cyanobacteria?
Cyanobacteria appear coloured because they contain the photosynthetic pigments chlorophyll (green) and photocyanin (blue). This means that they can produce their own food.
