The term "integument" refers to the protective outer covering of an organism. In humans and many animals, this includes the skin, hair, nails, and associated glands. The integument serves various functions, such as protecting against environmental hazards, regulating temperature, and providing sensory information. In plants, the integument can refer to the outer layers of seeds or the protective covering of leaves and stems. This layer helps prevent water loss and protects against pests and diseases. Overall, the integument plays a crucial role in the survival and health of both animals and plants.
