Question

Closed stomata reduces

• A. Rate of transpiration
• B. Amount of carbon dioxide entering the leaf
• C. Rate of respiration
• D. Both rate of transpiration and amount of carbon dioxide entering the leaf

Answer 1

The correct option is D Both rate of transpiration and amount of carbon dioxide entering the leaf

Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters. Therefore a closed stomata results in reduced rate of transpiration or loss of water as well as a reduction in the amount of carbon dioxide entering the leaf.
