This document summarizes three main types of plant habitats: terrestrial, aerial, and aquatic. Terrestrial plants live on land and have stiff stems and roots to support their growth and access to sunlight, water, and nutrients from the soil. Aerial plants live attached to other surfaces above the ground and obtain moisture and nutrients from the air. Aquatic plants live in water and have adapted leaves, stems, and roots suited to their water environment, such as leaves that float or roots that absorb oxygen.
