The water plant ia classified into

The water plants are classified into three groups :

1. Marginal and Emergent
Marginal plants are found along the edges of a pond or in shallow bogs where the roots are attached to muddy bottom. These plants are often called Emergents because portions of their stems grow above water.

2. Floaters
Floaters grow further from the edge, between shallow and deep water. These plants have leaves that float on the surface instead of below or above the surface.

3. Submerged
A third group of plants grow completely submerged under the surface of the water. They are often referred to as oxygenators. These plants help combat algae by consuming excess nutrients. They also provide cover for fish and produce oxygen during daylight hours. Roots of these plants are not used for nutrient or water uptake, but only for anchorage.
