What is the definition of a free-floating plant?

An aquatic plant that is anchored in sediment

An aquatic plant that floats freely on or beneath the water surface

The definition of a free-floating plant refers to an aquatic plant that floats freely on or beneath the water surface. These plants are not anchored in the substrate, which distinguishes them from submerged or rooted aquatic plants. Free-floating plants often have leaves that rest on the surface of the water to absorb sunlight and may also have roots that dangle in the water column. Examples of free-floating plants include duckweed and water hyacinth.

This definition is pivotal in understanding aquatic ecosystems, as free-floating plants contribute to habitat structure, provide cover for aquatic organisms, and play essential roles in processes such as photosynthesis and nutrient cycling in water bodies.
