What is aerenchyma?
Aerenchyma:
Aerenchyma is a modified parenchymatous tissue containing air chambers between cells. Function: These cells facilitate the diffusion of gasses between the plant and its surroundings and provide buoyancy to aquatic plants.
Example: It is mainly found in aquatic plants like lotus and water hyacinths as these cells help the plant float on water. The plant develops from the bed of the water body, but grows towards the surface and remains buoyant on the surface.
