Detailed explanation-1: -Waxy cuticles, trichomes (leaf hairs), sunken stomata, and other leaf adaptations also help reduce transpiration rates by keeping the leaf surface cool or protecting it from air currents that increase evaporation.

Detailed explanation-2: -The process of transpiration keeps the cell turgid, cools the surface of the leaves, and helps in the movement of minerals from the soil to different parts of the plant.

Detailed explanation-3: -Transpiration also provides the driving force for transport of water and nutrients from roots to shoots. Consequently, transpiration processes affect the yield and survival of agricultural species, and impact on the global carbon and hydrological cycles.

Detailed explanation-4: -fewer leaves offer less opportunity for transpiration, so the rate will do down. (The rate of transpiration is constant per cm square of area.
