Question

Which one of the following have high CO₂
compensation point ?
(a) C₂ plants (b) C₃ plants
(c) C₄ plants (d) Alpine herbs

Answer 1

(b) C₃ plants have high CO₂  compensation point

Explanation:

At the carbon dioxide compensation point, the rate of photosynthesis is equal to the rate of respiration. Therefore no net evolution of carbon dioxide.

The process of photorespiration in C3 plants increases the output of carbon dioxide. Consequently the compensation point is achieved at a higher atmospheric carbon dioxide concentration.

So, the correct option is 'C₃ plants'
