Floating Plants

These plants either float freely on the surface deriving their nutrients directly from the water via root systems or cell wall interactions.

Floating plants have leaves that float on the surface and are not rooted in the bottom sediment. Common species include:

Submerged Plants

These plants are completely underwater and are generally rooted in the bottom sediment. If flowers exist, they may extend above the surface of the water. Common species include:
