Submerged aquatic vegetation consists of rooted, vascular, flowering plants that grow underwater in freshwater, estuarine or marine habitats.

As their name suggests, submerged aquatic plants are macrophytes that grow primarily below the water’s surface. Some species are rooted to bottom sediments and others are free-floating.

Submersed plants are rooted at the bottom and grow up through the water. Flowers or flowering spikes often emerge above the water surface.

Submerged plants are rooted plants with flaccid or limp stems and most of their vegetative mass is below the water surface, although small portions may stick above the water.
