Vacuoles are empty, circular organelles, that help in the storage of food material or waste material.
Vacuoles are larger in plants than in animals.
As there is a lesser need to store water content, and nutrient content in animal cells, they do not need vacuoles like plants.
For the purpose of discharge of waste material, lysosomes are present in animal cells.
Compared to other cells, animal cells have smaller vacuoles, as they do not require the storage of more water, organic and inorganic for the proper functioning of the cell.
The animal cells, in muscular tissues, are devoid of vacuoles due to no requirement or usage of vacuoles.
