cuticle -- 1) In animals, a multilayered, extracellular, external body covering, usually composed of fibrous molecules such as chitin or collagen, and sometimes strengthened by the deposition of minerals such as calcium carbonate. 2) A waxy layer ...
cuticle A film composed of wax and cutin that occurs on the external surface of plant stems and leaves and helps to prevent water loss.

A number of approaches have developed, such as the development of waterproof skin (in animals), living in very moist environments (amphibians, bryophytes), and production of a waterproof surface (the cuticle in plants, ...
The upper surface is covered with a waxy, waterproof cuticle, which serves to reduce water loss from the leaf.

The epidermis of the leaf also functions in a more specialized manner by secreting a waxy substance that forms a coating, termed the cuticle, on the surface of the leaf.
They may also have a thickened cuticle to protect themselves from the environment. The stomata may be sunken into pits. Some xerophytes shed their leaves during the driest seasons and others can store water such as cacti.
Integument: The outer covering of the insect body that includes the cuticle and the epidermis.
Later, evolutionary developments such as a waxy cuticle allowed some plants to exploit more inland environments. Still mosses lack true vascular tissue to transport fluids and nutrients.
