Water hyacinth floats on surface of water because the parenchyma tissue present in water hyacinth has specialized tissue modification which is called Aerenchyma. This tissue has large air cavities due to which it provides the buoyancy to the plant and helps to float in the water.

Water hyacinth is large aquatic plant which doesn’t has any attachment with the bottom of water body and it always remains visible floating on surface of water body.
