Which outcome occurs in hot, arid climates when a C3 plant's stomata close to conserve water, impacting photosynthesis?

💡 Explanation

When stomata close, carbon dioxide uptake decreases, and oxygen concentration increases because continued photosynthesis releases oxygen. Rubisco then catalyzes photorespiration because it binds to oxygen instead of carbon dioxide, reducing photosynthetic efficiency. Therefore photorespiration increases, instead of enzymes operating better, chlorophyll accelerating, or CO2 fixation being unaffected.
