Question

In periods of hot, dry weather, the small pores (holes) on the surface of leaves of most plants will close in order to reduce water loss. When these pores are closed, carbon dioxide is restricted from entering the leaf. As a result, what product will also decrease? a. Cellular respiratory b. Water c. Glucose d. Carbon dioxide

Answer 1

c.Glucose

The stomata of plants will close during hot and dry day. This cause a decrease in concentration of carbon dioxide and increase in oxygen concentration in the plant. Photorespiration occur.

As carbon dioxide in photosynthesis is used to produce glucose molecules, the production of glucose molecule will decrease.
