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.

a decreased rate of photosynthesis.

Explanation:

Stomata are the entry point for CO₂, a key reactant in photosynthesis (which uses CO₂ to produce glucose). Closing stomata reduces CO₂ intake, limiting the rate of photosynthesis. Cellular respiration uses glucose and oxygen, so it is not directly increased by reduced CO₂. Cellular processes (like photosynthesis) will change, so no change is incorrect.

Answer:

a decreased rate of photosynthesis.
