Vacuoles are formed by the fusion of multiple membrane vesicles and are effectively just larger forms of these.
Endocytosis
Vesicles are responsible for transportation in and out of a cell. In some cases vesicles are used for storage also.

Vesicles perform many functions through complex mechanisms that can involve many aspects of cell regulation. Secretory vesicles in particular are specialized vesicles formed in the trans-golgi apparatus for releasing a product (such as molecule or protein) outside the cell. Secretory vesicles are used for exocytosis. Mast cells use secretory vesicles to release histamine which is a molecule involved immune response. Neurotransmitters can also be transmitted in secretory vesicles from nerve cells.
