Which type of aquatic plants float on the surface of the water?

Floating plants are specifically adapted to live on the surface of the water, where they can take advantage of sunlight and atmospheric carbon dioxide for photosynthesis. These plants have features that allow them to float easily, such as a light structure and air-filled tissues, which help them stay buoyant. Examples of floating plants include water lilies and duckweed.

In contrast, submergent plants grow fully underwater and are adapted to remain submerged, while emergent plants are anchored in the sediment and extend above the water surface. Algae, though often present in aquatic environments, are typically microscopic and can exist throughout the water column rather than being large, recognizable floating plants. Understanding these distinctions is important for managing aquatic ecosystems and recognizing the roles that these different types of vegetation play in maintaining water quality and habitat.
