The term for plants that can grow in water is "hydrophytes." These aquatic plants are uniquely adapted to survive in water-saturated environments, such as ponds, lakes, and wetlands. Hydrophytes can be fully submerged, partially submerged, or floating on the water's surface. They play a crucial role in aquatic ecosystems by providing habitat and food for various organisms, stabilizing sediments, and improving water quality by filtering pollutants. Common examples of hydrophytes include water lilies, cattails, and duckweed, each adapted to thrive in their specific aquatic habitats.
