- ii. Phloem cells transport food.
- iii. Sclerenchymatous cells give support to the plants
- iv. Parenchymatous cells store surplus food.
As these cells perform different functions they show great variation in shapes and sizes. Despite the structural and functional diversity, the plant cells have s common plant of organization.
