A cuticle /ËkjuËtÉªkÉl/ , or cuticula, is a term used for any of a variety of tough but flexible, non-mineral outer coverings of an organism, or parts of an organism, that provide protection. Various types of cuticle are non-homologous, differing in their origin, structure, function, and chemical composition.he cuticles of plants function as permeability barriers for water and water-soluble materials. The cuticle both prevents plant surfaces from becoming wet and helps to prevent plants from drying out. Xerophytic plants such as cactus have very thick cuticles to help them survive in their arid climates.
For example, the arthropods' cuticle is the outermost covering above the epidermis and that which forms the exoskeleton. In plants, the cuticle is the waxy covering on the surface of many of plant organs, e.g. leaves and young shoots. In plants, this waxy, hydrophobic covering protects the plant by minimizing water loss and curbing pathogen entry.
