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.
Cells are the basic building blocks of all living things. In order for organisms to survive, their cells must be able to complete numerous functions. Many of these functions require the cells to move molecules from one part of the cell to the other. When a cell needs to move a molecule many times, it uses vesicles. Vesicles are cellular organelles that are composed of a lipid bilayer. You can think of vesicles as cellular envelopes that are used to transport materials from one place to another. Vesicles also function in metabolism and enzyme storage as well.
