Question

In blue-green algae, the product of photosynthesis is

• A. Glycerol phosphate.
• B. Glycogen like.
• C. Glucoside.
• D. Glycerol.

Answer 1

Answer: (B)

Glycogen like.

Blue-green algae or cyanobacteria are the type of bacteria with prokaryotic organization. They are blue in colour due to the presence of phycocyanin and have other pigments such as phycoerythrin, chlorophyll A, and carotenes. They are the only prokaryotic organisms which are able to produce oxygen and carry out photosynthesis due to the presence of chlorophyll. The reserve food material is in the form of starch which is similar to glycogen and known as cyanophycean starch. Thus the correct option is B.
