Oxygen is not produced during photosynthesis by

A

Cycas

B

Nostoc

C

Green sulphur bacteria

D

Chara

Text Solution

Verified by Experts

The correct Answer is:
C
Green sulphur bacteria are anaerobic bacteria. They do not evolve oxygen during photosyntheis. Such type of photosynthesis is known as anoxygenic photosynthesis. The not use water as source of reducing power. Instead, hydrogen is obtained from hydrogen sulphide.
`underset("sulphate")underset("Hydrogen")(H_(2)S)rarr2[H]+S`
`6CO_(2)+12H_(2)overset("Light")underset("Enzymes")rarrC_(6)H_(12)O_(6)+6H_(2)O`
Concept Enhancer Green sulphur bacteria, e.g. Chlorobrium limicola , possesses bacteriophaeophytin as photosynthetic pigment .
Cycas is a gymnosperm, Nostoc is a blue-green algae and Chara is a green algae . All of these produce oxygen during photosynthesis.
