The term for plants that thrive in aquatic environments is "hydrophytes," also known as water plants or aquatic plants. These plants are specially adapted to living in water or saturated soil conditions. Hydrophytes can be found in various forms, including submerged, floating, and emergent types. Common examples include water lilies, cattails, and duckweed. They play crucial ecological roles by providing habitat and food for aquatic organisms, improving water quality through filtration, and facilitating nutrient cycling within ecosystems. Additionally, hydrophytes contribute to the aesthetic value of water bodies and are often utilized in landscaping and aquarium settings.
