Question

The rate of transpiration in desert planning a is reduced due to presence of _______.

Answer 1

hey

As the relative humidity of the air surrounding the plant rises the transpiration rate falls. It is easier for water to evaporate into dryer air than into more saturated air. Wind and air movement: Increased movement of the air around a plant will result in a higher transpiration rate.

ans. relative humidity

Answer 2

hello, dear

ans. is cuticles

(reason)

Cuticle are protective, hydrophobic waxy covering produced by epidermal cells of leaves, young shoots and other aerial parts. It minimises the water loss through transpiration (with the help of stomata) and also reduces pathogen entry. Lignin hardens the cell wall and provides flexibilty, tensile and compressional strength to the cell wall. Suberin is present in cork cells and makes the cell impervious to water.

hope it will help u

if u like my ans. plzzzz mark me as brainileast

thnx
