Question

Differentiate chlorenchyma and aerenchyma.......

Answer 1

in case of photosynthesis the parenchyma makes the food
and in arenchyma
in aquatic plants parenchyma provides the buoyency to plants to float

Answer 2

Aerenchyma: A spongy or soft plant tissue with large air spaces found between the cells of the stems and leaves of many aquatic plants, which allows exchange of gases between the shoot and the root. Aerenchyma also provides buoyancy, so the plants can easily float on the water. Chlorenchyma: In some cases the parenchyma cells contain chloroplasts and are called as chlorenchyma. These cells are meant for photosynthesis.
