Final answer:
A cuticle is a waxy coating on a plant that acts as a protective layer against water loss, UV radiation, pathogens, and pests.
Step-by-step explanation:
A cuticle is a waxy coating on the surface of a plant, primarily found on leaves and stems. It serves as a protective layer that helps prevent water loss and protects the plant from pathogens, UV radiation, and pests. The cuticle also helps reduce evaporation by creating a barrier between the plant's internal tissues and the external environment.
