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 membranous sacs found in plant and animal cells. Those in plant cells tend to be larger than those in animal cells. They are like storage tanks and they can con â¦ tain H2O, food, waste, or enzymes.
