Question

Photosynthesis of blue-green algae is

• A. Oxygenic
• B. Non-oxygenic
• C. Oxygenic and Non-oxygenic
• D. None of the bove

Answer 1

Answer: (A)

Oxygenic

Photosynthetic blue-green algae like Anabena include photosynthetic, oxygenic cyanobacteria. They contain a blue pigment along with chlorophyll. They may be nitrogen fixer and thus they are able to fix both nitrogen and carbon. Through the process of photosynthesis, they produce oxygen as a byproduct. Thus, the correct answer is option A.
