Question

3.1.9 - 12.e when the water availability of a plants environment decreases, the plant can respond by closing its stomata. this reduces the amount of water that the plant loses through its leaves due to transpiration. closing the stomata also reduces the amount of carbon dioxide that the plant can take in through its leaves, which will most likely result in?an increased rate of cellular respiration.no change in the cellular processes of the plant.an increased rate of photosynthesis.a decreased rate of photosynthesis.

Explanation:

Photosynthesis requires carbon dioxide as a reactant. When stomata close, less carbon dioxide enters the plant. According to the principle that reactant availability affects reaction rate, a decrease in carbon dioxide will slow down photosynthesis. Cellular respiration is not directly increased by this (it has its own set of factors like oxygen and glucose availability). And since photosynthesis is affected, there is a change in cellular processes.

Answer:

a decreased rate of photosynthesis.
