Q4 / 180 · NEET 2014 · Botany

Anoxygenic photosynthesis is characteristic of:

  • Correct answer
    A
    Rhodospirillum
  • B
    Spirogyra
  • C
    Chlamydomonas
  • D
    Ulva

Solution

The photosynthetic bacteria respire without oxygen. No oxygen is evolved in bacterial photosynthesis. Water is not used as a source of reducing power. Instead, hydrogen is obtained either directly or from various types of inorganic and organic compounds, e.g., H2​S, aliphatic compounds. Anoxygenic photosynthesis is characteristic of Rhodospirillum. It is a non-oxygenic photosynthetic bacteria.

Hence, the correct answer is option: 'A'.
