Form of endocytosis during which liquids are taken into the cell through the invagination of the cell membrane.
The engulfment of liquids or very small particles by phagocytic cells.
when the vesicle formed from endocytosis contains droplets of fluid.
pinein = to drink + kytos = cell + osis = a condition of; process by which a cell takes in droplets of fluid.
Gr.: drinking cell] • A form of endocytosis; the uptake of liquids by engulfing a sample of the external medium into a pocket of the plasma membrane followed by pinching off the pocket to form an intracellular vesicle. (Contrast with phagocytosis and endocytosis.)
The nonspecific uptake of small droplets of extracellular fluid into endocytic vesicles.
process by which certain cells can engulf and incorporate droplets of fluid
pine-o-si-TOE-sis A protozoan cell pinches inward and brings fluid into the cell. 459
(pihn'-o-sih-TO-sihs) A type of exocytosis in which bulk amounts of fluid are transported into the cell.
uptake of fluids and colloids by minute invaginations of the cell membrane to form fluid-filled vacuoles; does not require an energy source.
Ingestion of liquid or very small particles by vesicle formation in a cell.
A form of endoctyosis in which fluids enter the cell; 'cell drinking'
Uptake of materials into cell by means of 'pinching off' of small membrane-bound vesicles.
In cellular biology, pinocytosis ("cell-drinking") is a form of endocytosis, a process in which small particles are taken in by a cell by splitting into smaller particles. The particles then form small vesicles which subsequently fuse with lysosomes to hydrolyze, or to break down, the particles. This process requires adenosine triphosphate (ATP), the chemical compound used as energy in a majority of cells.
