5.11: Vesicles and Vacuoles, Lysosomes, and Peroxisomes
WebVesicles 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 5.11.1 5.11. 1 ).
