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.
As stated earlier, the primary function of the central vacuole in plant cells is to maintain the turgor of the cell. Turgor is the pressure exerted on the cell wall by the contents of the cell.The central vacuole determines the amount of turgor based on it water content as a result of osmotic pressure.n plant cells, however, there is generally a large single central vacuole. Comprising approximately 90% of an mature plant cell, the central vacuole provides structure and support to the cell by maintaining turgor pressure, which is essentially fluid pressure that keeps the cells rigid.
