Answer:
The root-system in hydrophytes is feebly evolved and root hairs and root cap are absent. In some floating plants such as Utricularia, Ceratophyllum, etc., no roots are evolved, and in submerged plants such as Vallisneria, Hydrilla, etc., water dissolved mineral salts and gases are absorbed by their whole surface.
