Detailed explanation-1: -A thick, waxy coating of cutin is present on the epidermis of desert plants . It helps in reducing the loss of water in desert plants. Suberin, which is also a chemical, is present in the walls of dead cork cells. It makes these cells impervious to gases and water.

Detailed explanation-2: -cuticle. It consists of cutin, a waxy, water-repellent substance allied to suberin, which is found in the cell walls of corky tissue. Cutin is especially noticeable on many fruits-e.g., apple, nectarine, and cherry, which can be buffed to a high gloss.

Detailed explanation-3: -A cuticle is a waxy layer present on a young stem’s epidermis that normally cuts water loss through transpiration.

Detailed explanation-4: -Cutin composes the macromolecular frame of the plant cuticle in which the low molecular waxes and fats are embedded. Together, they form the cuticle. The cuticle covers the epidermis and protects the surface of plants against desiccation by the atmosphere.

Detailed explanation-5: -Cutin is one of two waxy polymers that make up the plant cuticle, which covers all of the plant’s aerial surfaces. Cutin is a waxy-water insecticidal substance found in plant cuticles that is composed of highly polymerized esters of fatty acids.
