Tonoplast is the outer covering of vacuole
The outer membrane of a vacuole is typically referred to as the tonoplast. It acts as a selective barrier that controls the movement of substances into and out of the vacuole.
Vacuoles, organelles that are present in all plant and fungal cells as well as those of other organisms (animal, bacterium, protist), are closed compartments containing molecules enclosed by water. This organelle therefore serves many functions.The primordial utricle and the tonoplast are examples of cytoplasm that is present around the vacuoles of plants.
