Uptake of fluid-filled vesicles into cells (endocytosis). Macro-pinocytosis and micro-pinocytosis are distinct processes, the latter being energy independent and involving the formation of receptor-ligand clusters on the outside of the plasma membrane, and clathrinon the cytoplasmic face.
In protozoa, the uptake of macro-molecules into a cell by a drinking type of action.
In cellular biology, pinocytosis is a mode of endocytosis in which small particles are brought into the cell, forming an invagination, and then suspended within small vesicles. These pinocytotic vesicles subsequently fuse with lysosomes to hydrolyze (break down) the particles. This process requires a lot of energy in the form of adenosine triphosp...Found on http://en.wikipedia.org/wiki/Pinocytosis
(pin;uo-si-to;sis) Cell drinking; invagination of the cell membrane forming narrow channels that pinch off into vacuoles. This allows for cellular intake of extracellular fluid and dissolved molecules.Found on http://www.mhhe.com/biosci/abio/glossary.mhtml
(pin″o-) (pi″no-si-to´sis) a mechanism by which cells ingest extracellular fluid and its contents; it involves the formation of invaginations by the cell membrane, which close and break off to form fluid-filled vacuoles in the cytoplasm. adj., pinocytot´ic., adj. ...Found on http://www.encyclo.co.uk/local/21001

A process of ingesting material by enclosing it with a membrane. The resulting structure is usually too small to be seen with the light microscope and is mostly suitable for the ingestion of fluid or mucus. Found on http://tolweb.org/tree/home.pages/glossary.html
An amoeba showing pinocytosis The process by which a cell takes in extracellular fluid by the invagination of the cell membrane. The pocket then pinches off to form a vesicle, which subsequently ruptures, releasing its contents into the cytosol.

Pinocytosis: A cellular process that permits the active transport of fluid from outside the cell through the membrane surrounding the cell into the inside of the cell. In pinocytosis, tiny incuppings called caveolae (little caves) in the surface of the cell close and then pinch off to form pinosomes, little fluid-filled bubbles, that are free withi...Found on http://www.medterms.com/script/main/art.asp?articlekey=14505
