Solution


Q.

Oxygen is not produced during photosynthesis by:  [2018]
1 Green sulphur bacteria  
2 Nostoc  
3 Cycas  
4 Chara  

Ans.

(1)

Green sulphur bacteria do not have the ability to use water as an electron donor (or cannot oxidise water), instead they perform photosynthesis using sulfide. Therefore, they do not evolve oxygen during photosynthesis.
