Write the adaptation in aquatic plants due to which leaves can float on the surface of water.. ans me fast​

Aquatic plants float on water because they have buoyancy because of the presence of large air cavities in their parenchyma(the functional tissue of an organ as distinguished from the connective and supporting tissue.), and the parenchyma is known as aerenchyma(a soft plant tissue containing air spaces, found especially in many aquatic plants.). This makes them float on water.
