Vesicles and Vacuoles Vesicles and vacuoles are membrane-bound sacs that function in storage and transport. Vacuoles are somewhat larger than vesicles, and the membrane of a vacuole does not fuse with the membranes of other cellular components. Vesicles can fuse with other membranes within the cell system (Figure 1).
Vacuoles are stationary while the vesicles are mobile. Vacuoles are used for storage or digestion purposes for different kinds of cells. There are three types of vacuoles; food vacuoles, contractile vacuoles, and central vacuoles. Vesicles are little transfer ships. Two types of vesicles are transport vesicles and secretary vesicles.
