Assertion : Cyanobacteria perform oxygenicphotosynthesis.
Reason : Cyanobacteria posses chloroplasts.

Options

A. Both Assertion and Reason are true and Reason is the correct explanation of Asseration

C. Assertion is true , but Reason is false
D. Assertion is false, but Reson is true

Answer

C

Explanation

Cyanobacteria or blur -green algae are prolaryotic organisms , but they perform oxygenic photosynthesis, i.e, they evolve oxygen during photosynthesis . They do not possess chloroplasts as found in photosynthesising eukaryotes. Chloroplast is a double membrane bounded cytoplasmic organelle present in all photosynthesising eukaryotic cells and absent in all prokaryotic cells.
