A: A vesicle is a small membrane-bound sack that stores and transports substances throughout the cell. They can form naturally within the cell to aid in cellular secretion such as exocytosis, endocytosis or phagocytosis or they can be artificially prepared by chemists and biologists.
Vesicles perform a variety of functions. 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.
