Which process is directly inhibited when atmospheric humidity increases around plant leaves?

A)Transpiration due to decreased vapor pressure.
B)Guttation due to reduced root pressure.
C)Phloem transport of sugars increases.
D)Active transport of ions accelerates.

💡 Explanation

Transpiration decreases as humidity increases because reduced difference in water potential affects water vapor diffusion. Therefore, water movement from the leaf slows, rather than other transport processes like guttation or nutrient flow being affected.
