If a leaf receives enough light but its stomata remain closed for a long time, why can the rate of photosynthesis decrease?

Answer and explanation

Correct answer: Carbon dioxide entry into the leaf will decrease

The correct answer is B. Closed stomata reduce the diffusion of carbon dioxide from the air into the leaf. Because carbon dioxide is a raw material for photosynthesis, its reduced availability can lower the rate even when there is enough light.
