Which adaptive outcome results when desert plants initiate nocturnal stomatal opening?

A)Reduced transpirational water loss during heat
B)Enhanced photosynthetic rate in arid conditions
C)Increased oxygen production during nighttime
D)Accelerated nutrient uptake from dry soils

💡 Explanation

Nocturnal stomatal opening utilizes CAM photosynthesis for fixing CO2 at night via vacuole storage, because this minimizes water loss through transpiration rather than allowing daytime CO2 intake; therefore, water is conserved, rather than used quickly during high heat.
