Vacuoles are generally used to store cell products or protect the rest of the cell from invading microorganisms. The large central vacuole of plant cells is a special case. It is used to store water and cellular wastes and helps maintain the necessary internal pressure of plants called turgor pressure. Structure.

The central vacuole determines the amount of turgor based on it water content as a result of osmotic pressure.
