The vacuole of a plant(6 in image) is formed by the addition of many vesicles from the endomembrane system. The outer membrane of the plant vacuole is called the tonoplast. In many plants, the vacuole contains digestive enzymes similar to those found in a lysosome. Breakdown of the tonoplast can cause the acids and enzymes to digest the cell, an important process in the ripening of some fruit. The acidic juices of citrus fruits are contained in the lysosome/vacuole of the cell.
