Answer 2

Answer:

Option a) Oxygenic and non-oxygenic is the correct option. Photosynthesis in green algae and bacteria is respectively oxygenic and non-oxygenic.

Explanation:

Oxygenic Photosynthesis- It is a non-cyclic electron chain that occurs in the presence of sunlight where the water is taken up by the plant roots, initially donates an electron, and becomes oxidized, transfers the electron to the carbon dioxide which itself gets reduced to produce carbohydrates and molecular oxygen.

• It occurs in plants, cyanobacteria, and algae. It occurs in the chloroplasts of the cell.

Anoxygenic or non-oxygenic photosynthesis occurs only in bacteria but not in green algae. In which photosynthesis occurs without the production of oxygen.

• Some examples of anoxygenic bacteria are- species of Rhodospirillum from phylum proteobacteria or purple bacteria and green sulfur bacteria which belongs to phylum Chlorobi.
