Hydrophytes that are partially submerged have floating leaves with stomata through which gases can be exchanged as in land plants

Answer:

The floating roots are swollen spongy and have large aerenchyma. They provide buoyancy to the plant and are also respiratory in function. These are found in Jussiaea, Utricularia. The roots are covered by a hygroscopic velamen tissue which absorbs water from the atmosphere.
