Question

water hyacinth floats on water. why is this?

Answer 1

Water hyacinths are the only large aquatic herb that can float on the water unattached to the bottom. They float on bloated air-filled hollow leaf stalks. The leaves of free-floating water hyacinths are characterised by a bulbous swelling in a section of the petiole. The oxygen bubbles float to the surface of water and get released into the air which provides buoyancy. (0)

Answer 2

Water hyacinth float on water surface because of the presence of the air cavities present in the parenchyma tissue.
