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).
Vesicles are small cell organelles that are present in cells. These organelles are small, membrane enclosed sacs which store and transport substances to and from one cell to another and from one part of a cell to another.They are one of the important parts of a cell.The vesicle is separated from the rest of the cytoplasm by at least one phospholipid bilayer.hese organelles are small, membrane enclosed sacs which store and transport substances to and from one cell to another and from one part of a cell to another.
