Because it is separated from the cytosol, the inside of the vesicle can be made to be different from the cytosolic environment. For this reason, vesicles are a basic tool used by the cell for organizing cellular substances.Vesicles are involved in metabolism, transport, buoyancy control, and enzyme storage.acuoles are vesicles which contain mostly water. 1  Plant cells have a large central vacuole in the center of the cell that is used for osmotic control and nutrient storage. 2  Contractile vacuoles are found in certain protists, especially those in Phylum Ciliophora.
