A vacuole is a membrane-bound organelle that can store any variety of materials for a cell including food and nutrients that the cell will use, or even wastes that the cell will get rid of. 

Both plant and animal cells have vacuoles. In plant cells the vacuole is very large and helps to provide the turgor pressure necessary to keep plant cells rigid and the plant upright. In animal cells there are multiple small vacuoles. 

Vacuoles can be formed by smaller membrane-bound organelles, vesicles, fusing together. Vesicles are used for transporting molecules to and from the cell membrane to either take in molecules or release molecules through endocytosis and exocytosis. 

Vacuoles are perfect for separating anything the cell doesn't want exposed to the rest of the cell. In the case of wastes, some substances can be harmful for the cell, and the vacuole can store these wastes until they are either released or broken down by lysosomes. Vacuoles are extremely versatile storage organelles that can provide a variety of functions for the cell.

what does a vacuole do?

A vacuole is a cell organelle; is it basically a membranous bag filled with fluids. Vacuoles store water and certain materials that are water-soluble. They are present in all plant and fungi cells. They are also found in some species of bacteria and in some animal cells.

In plants and fungi, vacuoles store water and some pigments, and they also provide turgor pressure to support the cells from within. In general, they are larger and more obvious in the plant and fungus cells than in the other organisms discussed here.

In bacteria vacuoles are believed to be a storage organelle. In animals they are used for storage and can be created through the process of pinocytosis. Some types of single-celled animals in the protist group have a special kind of vacuole known as a contractile vacuole, which can gather excess water from inside the cell and expel it into the environment.
