NEET BIOLOGY

Detailed explanation-1: -Cuticle – It is an epidermal layer seen in vascular plants, cells of this layer release cutin which is a waxy substance, preventing water loss from the stomata.

Detailed explanation-2: -So the leaf has another adaptation to reduce water loss: the waxy cuticle, so called because it is made out of a water-repellent substance called cutin.

Detailed explanation-3: -Plants have evolved over time to adapt to their local environment and reduce transpiration. Leaves are covered by a waxy cuticle on the outer surface that prevents the loss of water.

Detailed explanation-4: -A waxy layer known as the cuticle covers the leaves of all plant species. The cuticle reduces the rate of water loss from the leaf surface. Other leaves may have small hairs (trichomes) on the leaf surface.

Detailed explanation-5: -Thick waxy cuticle: The cuticle cuts down water loss in two ways: it acts as a barrier to evaporation and also the shiny surface reflects heat and so lowers temperature. Sunken stomata: Stomata may be sunk in pits in the epidermis; moist air trapped here lengthens the diffusion pathway and reduces evaporation rate.
