Question

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 (1 point) an increased rate of photosynthesis. a decreased rate of photosynthesis. an increased rate of cellular respiration. no change in the cellular processes of the plant.

Explanation:

Photosynthesis requires carbon - dioxide as a raw material. When stomata close, less carbon - dioxide enters the plant. With less carbon - dioxide available, the rate of the photosynthetic reaction will decrease.

Answer:

B. a decreased rate of photosynthesis
