This document discusses the types of aquatic plants that grow in water. There are three main types: fixed plants, which have roots fixed to the bottom and hollow, flexible stems; floating plants, which have spongy stems that allow them to float freely without roots; and underwater plants, which have thin, tiny leaves and long, flexible stems that move with the water.
