Vacuoles – Definition
Vacuoles are membrane-enclosed sacs within the cell. It is a type of vesicle. It mainly function is to store water in the animal and plant cells. Plant cells have a large, central vacuole mostly stored water and nutrients. In animal cells there are many small vacuoles found in the cell which carry on the process of endocytosis and exocytosis.
