Question:
Which of the following do not evolve $O_2$?
Which of the following do not evolve $O_2$?
Updated On: Aug 15, 2022
- green algae
- blue-green algae
- autotrophic plants
- photosynthetic bacteria
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Photosynthetic bacteria are of 2 types - phototrophs and chemotrophs . Phototrophs carry out photoprepare their food using chemicals from surrounding medium. Photosynthetic bacteria shows only cyclic photophosporylation where splitting (photolysis) of water does not take place. Hence, $O_{2}$ is not released.

Processes Of Photosynthesis in Higher Plants:
Photosynthesis in higher plants involves the following processes:
- Light Reaction
- Dark Reaction
Light Reaction:
- This phenomenon occurs in the presence of light.
- The pigment absorbs light and produces energy in the form of ATP.
- The process involves- absorption of light, water splitting, the release of oxygen, and formation of ATP and NADPH.
Dark Reaction:
This process occurs in the absence of light in the stroma of the chloroplasts. The following cycles are involved in the process:
- Calvin Cycle (C3 Cycle)
- C4 Cycle (Hatch and Slack Pathway)
