Pinocytosis is a type of nutrition intake in which small dissolved molecules are taken up by vesicles.
The process by which the cell takes in the liquids together with dissolved tiny molecules is known as pinocytosis (the Greek word pino meaning "to drink"). The cell membrane folds during this process, forming tiny pockets that catch the cellular fluid and dissolved material.
Extracellular fluid and solutes are suc-ked up into a cell via tiny vesicles during the vigorous, energy-intensive process known as pinocytosis. It is a particular instance of endocytosis, which describes a cell's ingestion of chemicals. The processes of phagocytosis and receptor-mediated endocytosis are other types of endocytosis.
