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.
Turgor pressure pushes the plasma membrane against the cell wall of  plant, bacteria, and fungi cells. An example of turgor pressure is  osmosis which causes water to flow f â¦ rom an area of low solute  concentration to an area of high solute concentration until the two  areas are equal. 1 person found this useful.
