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).
Peroxisomes breakdown fatty acids to sugars, also. It is easier to transport and use as a energy source. Vacuoles/vesicles are found in both animal and plant cells, although it is more of a plant cell organelle since animal cells have lysosomes. They are a membrane-bounded sac in the cytoplasm of some cells. 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.
