Regarding this, what is the cuticle of an insect?

The cuticle or exoskeleton is a protective integument over the external surface of insects. It is an extracellular matrix produced by the epidermis and consists mainly of proteins and the polysaccharide chitin (Tajiri, 2017). In addition to a physical barrier, the cuticle also provides an active biochemical barrier.

what is the function of the cuticle in terrestrial insects? The wax layer of the cuticle not only protects the insect from desiccation but forms a barrier for penetration of topically applied pesticides, which have to cross this hydrophobic boundary and then enter the hydrophilic environment of the endocuticle and the body cavity of the insect.

Keeping this in view, what is waxy cuticle made of?

In some higher plants, the cuticle is a water-impervious protective layer covering the epidermal cells of leaves and other parts and limiting water loss. It consists of cutin, a waxy, water-repellent substance allied to suberin, which is found in the cell walls of corky tissue.

What is the structure of the cuticle?

A plant cuticle is a protecting film covering the epidermis of leaves, young shoots and other aerial plant organs without periderm. It consists of lipid and hydrocarbon polymers impregnated with wax, and is synthesized exclusively by the epidermal cells.
