Synaptic vesicles contain thousands of neurotransmitter. The  neurotransmitters are packed into a small membrane bound synaptic  vesicles. There are thousands of neurotransm â¦ itter molecules.
Vacuoles 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.ecause 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.
