VESICLE

Vesicle

In cell biology, a vesicle is a small bubble within a cell, and thus a type of organelle. Enclosed by lipid bilayer, vesicles can form naturally, for example, during endocytosis. Alternatively, they may be prepared artificially, in which case they are called liposomes. If there is only one phospholipid bilayer, they are called unilamellar vesicles; otherwise they are called multilamellar. The membrane enclosing the vesicle is similar to that of the plasma membrane, and vesicles can fuse with the plasma membrane to release their contents outside of the cell. Vesicles can also fuse with other organelles within the cell.
