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 water-filled storage spaces found in cells. They are found in both animal and plant cells (but they are more common in plant cells they are also bigger in plant c â¦ ells). Vacuoles store food, collect waste products, and can help with cell shape and buoyancy.acuoles are water-filled storage spaces found in cells.
