Which outcome occurs when elevated CO2 causes decreased stomatal conductance during drought?

💡 Explanation

When elevated CO2 concentrations prompt stomatal closure during drought, transpiration decreases because reduced stomatal opening limits water vapor release, which reduces evaporative cooling. Therefore, transpiration cooling slows, rather than enhance nutrient absorption, root development, or chlorophyll production which need open stomata.
