Detailed explanation-1: -There is a waxy, waterproof coating covering the surface of the epidermis. This covering is called the cuticle. The cuticle is usually thicker on the upper surface of the leaf than on the underside.
Detailed explanation-2: -Leaves have an upper epidermis and a lower epidermis. The lower epidermis is located on the underside of leaves. This layer often has stomata (singular is stoma).
Detailed explanation-3: -Lower Epidermis: A protective layer of cells. The lower epidermis produces a waxy cuticle too in some plant species. The lower epidermis contains pores called stomata that allow carbon dioxide and oxygen to move in and out of the plant respectively.
Detailed explanation-4: -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.
