Water plants, also known as aquatic plants, are plants that grow in or near water bodies like lakes, rivers, and ponds. They can be fully submerged, partially submerged, or floating on the water's surface. These plants play a crucial role in their ecosystems by providing oxygen, serving as habitats for various aquatic animals, and helping to filter pollutants from the water. Common types of water plants include lilies, cattails, and duckweed. They can be found in both freshwater and saltwater environments. Water plants are essential for maintaining the health of aquatic ecosystems and contribute to biodiversity by supporting a wide range of wildlife.
