Anoxygenic photosynthesis is characteristic of (a) Rhodospirillum (b) Spirogyra (c) Chlamydomonas (d) Ulva.
Option A In Rhodospirillum, electron donor is organic compound instead of water hence no oxygen is released, i.e., anoxygenic photosynthesis occurs. In other plants water is used as electron donor and H + and O 2 are produced during photolysis of water.
