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 large vesicles that are derived from the Endoplasmic reticulum and Golgi apparatus. They are membrane- bound sacs and serve many functions such as storage. Animal cell vacuoles are much smaller and more numerous than plant... The region between the nuclear envelope and the plasma membrane is the cytoplasm. Within the cytoplasm of a eukaryotic cell are many different membrane bound organelles including vacuoles.
