Aquatic Plants


What is Aquatic Plants?
The plants that develop in freshwater or saltwater are called aquatic plants and derive their name from the word 'aqua' which means water.
Plants that float in water:
Some plants, like water hyacinth, float in water. They have special types of leaves that help them to stay afloat. They use sunlight and air to make their food.
Plants that grow under water:
Some plants grow under water. These plants take carbon dioxide from the water around them and give out oxygen. Tape grass, pond weed and hydrilla are such plants. Their leaves have no pores or stomata and they breathe through their surface. These plants are flexible and can bend easily with the flow of water.
Plants that are fixed in water:
Some plants like water lily and lotus have their roots fixed in the waterbed. Their stems are hollow and light so that the flowers and leaves can float on water. They breathe through the pores or stomata on their broad leaves.
