Question

What will be the effect on plant if stoma remains closed for a prolonged period of time

Answer 1

Explanation:

There will be no gas exchange. No carbon dioxide will move into the plant and there will not be any photosynthesis. There will be no transpiration. Transpiration helps in cooling of the plant. The plant may get burnt by heat. No transpiration = no water moving up the plant by transpiration pull. The leaves wont get water and won't photosynthesis. There will be no respiration at night ( as no gas exchange will take place).
