(i) Parenchyma cells contain chloroplasts and take part in photosynthesis, so they are known as chlorenchyma. Thus, they are meant for storage of food.
(ii) Paremchyma have fibre like prosenchyma which is meant for providing turgidity and strength.
(iii) Parenchyma in aquatic plants possess air spaces, and are known as aerenchyma which stores air and provides buoyancy to aquatic plants.
