Question

Why in floating aquatic plants, stem is thin and flexible?

Answer 1

1. Plants living or floating on the surface of water or slightly below it are called floating plants. For example water hyacinth (Eichhornia), water lily, and lotus.
2. These plants are not in contact with soil. These plants show adaptations in their roots, stems, and leaves.
3. Roots and root hair are poorly developed as they do not need to prop up the plant.
4. The stem is thin and flexible so that it can bend along with the water movement am pressure.
5. Leaves are large and circular and keep floating on the surface of the water.
