Question

If a plant's stomata were always closed, how would this affect the plant's ability to make glucose?

A. There would be no effect on the ability of the plant to make glucose
B. Plants would be able to make more sugar than normal
C. Plants would make less sugar than normal

Answer 1

Plants would make less sugar than normal if their stomata were always closed, as this would inhibit carbon dioxide intake and oxygen release, both of which are crucial for photosynthesis and the production of glucose.

Step-by-step explanation:

If a plant's stomata were always closed, it would significantly affect the plant's ability to make glucose. The stomata are crucial for the process of photosynthesis, as they allow carbon dioxide (CO2) to enter the leaves. Carbon dioxide is a necessary raw material for photosynthesis, which is the process by which plants make glucose using light energy. Furthermore, the closure of stomata would prevent oxygen (O2) from exiting the plant, leading to a buildup of O2 and a depletion of CO2 inside the leaf. Together, these effects would inhibit the rate of photosynthesis, leading to less sugar production. Consequently, plants would make less sugar than normal.
