Aquatic plants are plants that grow in or near water, including freshwater and saltwater environments. They can be found in various forms, such as floating, submerged, or emergent. Common examples include water lilies, cattails, and algae. These plants play a crucial role in aquatic ecosystems by providing oxygen, food, and habitat for various aquatic organisms. Aquatic plants are adapted to their watery surroundings, often featuring specialized structures like broad leaves to capture sunlight and roots that can anchor them in soft sediments. They also help maintain water quality by absorbing nutrients and filtering pollutants, making them essential for healthy aquatic habitats.
