Aquatic plants, also called hydrophytic plants or hydrophytes, include plants like the water soldier, water lily, duckweed, hydrilla, eelgrass and the floating fern, all of which have adapted to living in, on or next to water and can only grow either partially or completely submerged in water. These can be either free-floating, such as the water hyacinth, or have roots extending beneath the water to the ground, such as the lotus.
