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 formed by the fusion of vesicles, so in essence, they are larger and more effective versions of a vesicle. They act as miniature storage bins for plants and hold food and nutrients that are vital to the plantâs health. Vacuoles have many functions and are important players in the survivability of a plant. The structure of a vacuole consists of a membrane that encompasses a mass of fluid. The fluid is what contains the aforementioned nutrients or waste products.
