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).
Vacuole is an important organelle present in the cells of plants, animals, protists, fungi and bacteria. Apart from water, vacuoles also contains different kinds of organic/inorganic molecules, solid materials and enzymes.Vacuoles are kind of large-sized vesicles.he functions that vacuoles perform in different types of cells are listed below. Maintaining the turgor pressure and pH in cells are the important vacuole functions. Taking into account these and other functions mentioned above, we can say that vacuole plays an important role in the functioning of plant cells.
