Question

Quizplus · Accepted Answer

The value of photosynthetically active radiation above which no further increase in photosynthesis occurs is referred to as the light saturation point. At this point, the photosynthetic process is saturated and the rate of photosynthesis does not increase with further increase in light intensity. Option A refers to a condition where too much light can actually reduce the efficiency of photosynthesis. Option B refers to the level of light intensity required for a plant to produce enough energy to maintain its basic metabolic functions, while option C refers to the light intensity at which the rate of photosynthesis is exactly balanced by the rate of respiration.
