Detailed explanation-1: -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.

Detailed explanation-2: -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. Leaves enable photosynthesis to occur.

Detailed explanation-3: -The waxy covering on plant leaves, young stems, and fruit is called the “cuticle". It is composed of cutin, a wax-like material produced by the plant that is chemically a hydroxy fatty acid. The purpose of this covering is to help the plant retain water.

Detailed explanation-4: -The epidermis (from the Greek
