← Nature & AnimalsWhich 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.
