Detailed explanation-1: -Thick, waxy cuticle – having leaves covered by a thickened cuticle prevents water loss from the leaf surface. Stomata in pits – having stomata in pits, surrounded by hairs, traps water vapour and hence reduces transpiration.

Detailed explanation-2: -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. Trichomes help to avert herbivory by restricting insect movements or by storing toxic or bad-tasting compounds.

Detailed explanation-3: -To reduce water loss the leaf is coated in a waxy cuticle to stop the water vapour escaping through the epidermis. Leaves usually have fewer stomata on their top surface to reduce this water loss.

Detailed explanation-4: -The cuticle is a waxy substance that is present on the surface of leaves. It prevents excessive loss of water from the plant by transpiration.

Detailed explanation-5: -Abstract. Cuticle is the major transpiration barrier that restricts non-stomatal water loss and is closely associated with plant drought tolerance.
