Floating plants are typically defined as those that are able to float on the surface of the water, often utilizing buoyant structures or adaptations such as modified stems or leaf structures. Duckweed and watermeal are prime examples of this category, as they consist of small, often tiny, plant forms that thrive on the water’s surface. These plants play crucial roles in aquatic ecosystems, including providing habitat for various organisms and contributing to the overall productivity of the water body by facilitating oxygen production through photosynthesis.

In contrast, lily pads and cattails, while they do have parts that float or rise above the water, are not primarily classified as floating plants — lily pads are technically rooted aquatic plants with floating leaves, and cattails grow in marshy areas and typically do not float. Algae and plankton, while plentiful in aquatic environments, are classified differently; algae are photosynthetic organisms that can float but lack true plant structures, and plankton encompasses a diverse range of organisms, including tiny aquatic animals. Lastly, kelp and seagrass are marine plants that are usually found submerged rather than floating, contributing to different types of underwater ecosystems rather than the floating plants concept.
