Question

Which of the following graphs correctly depicts the rate of photosynthesis of sun plant (P) and shade plant (Q)?

Professor PC Thomas Classes · Answer

(d) : The rate of photosynthesis is more in intense light than diffused light. The light intensity is more in heliophytes (sun loving plants) and less in sciophytes (shade loving plants). For a plant, rate of photosynthesis increases with increase in light intensity except very high light intensity, which causes solarisation.
