The essential functions of roots are anchorage and absorption of water and minerals in the terrestrial plant. What functions are associated with the roots of aquatic plants? How are the roots of aquatic plants and terrestrial plants different?
As we know, the basic function of roots is that of anchorage and absorption of water and minerals. Availability of water is not an issue for aquatic plants. That is why the roots are not properly grown in most aquatic plants and are in the form of adventitious roots. In plants like Wolffia, they are even absent. In free-floating plants, the roots are very few and are in a structure of fine hairs. In the plants that are submerged, roots play an important role in anchorage.
