Question

Give an account of the inherent properties of the leaf which affect the rate of transpiration.

Answer 1

Inherent properties of leaves which affect the rate of transpiration are as follows:

1. Presence or absence of a cuticle layer on the surface of leaves. Cuticles help in water conservation in plants.
2. The number of stomata present on the leaves. More stomata, more transpiration.
3. Position of the stomata present on the leaves. Generally stomata present at the lower surface of leaves which reduce the transpirational loss of water.
4. The inclination of leaves, which reduces the rate of transpiration by reducing the effectiveness of sunlight.
