Anoxygenic photosynthesis is characteristic of
- Rhodospirillum
- Spirogyra
- Chlamydomonas
- Ulva.
Answer
(1) Rhodospirillum
Solution
In anoxygenic photosynthesis, water is not used as the electron donor, so O2 is not released; it occurs in photosynthetic bacteria having bacteriochlorophyll and only PS I.
∵ Rhodospirillum is a purple non-sulphur photosynthetic bacterium.
∵ Spirogyra, Chlamydomonas and Ulva are green algae which perform oxygenic photosynthesis.
∴ Anoxygenic photosynthesis is characteristic of Rhodospirillum.
