Describe the conflict between a plant's need to undergo photosynthesis and its need to conserve water when it is in short supply.Briefly state how plants overcome this problem. A)For photosynthesis to occur,plants need to take in O₂ and release CO₂.Plants accomplish this task by opening and closing the stomata on their leaves.Each time the stomata are open,however,plants also lose water vapor.If water is in short supply,this loss can decrease the rate of photosynthesis.To overcome this problem,plants undergo respiration. B)For photosynthesis to occur,plants need to take in CO₂ and release O₂.Plants accomplish this task by opening and closing the stomata on their leaves.Each time the stomata are open,however,plants also lose water vapor.If water is in short supply,this loss can decrease the rate of photosynthesis.To overcome this problem,plants undergo photorespiration. C)For photosynthesis to occur,plants need to take in CO₂ and release O₂.Plants accomplish this task by opening and closing the stomata on their leaves.Each time the stomata are open,however,plants gain water.This gain can decrease the rate of photosynthesis.To overcome this problem,plants undergo transpiration.

Option B correctly identifies the conflict between a plant's need for photosynthesis and its need to conserve water when water is in short supply. Plants overcome this problem by undergoing photorespiration. Option A incorrectly suggests that plants overcome this conflict by undergoing respiration, which is not directly related to their water-conserving efforts. Option C incorrectly suggests that plants gain water through transpiration, which is not accurate.
