Which phenomenon occurs when environmental conditions prevent optimum osmotic regulation through plant stomata?

💡 Explanation

An increase in photorespiration occurs when stomata close to conserve water, because decreased CO2 levels prevent efficient carbon fixation by rubisco, therefore photorespiration rises, rather than nitrogen fixation which would need a lot stomatal openings.
