Science glossary film: Endocytosis

The process by which a cell can take in material from its environment by first engulfing it with its cell membrane. This can work on a very small scale, involving single molecules. Or, on a larger scale, endocytosis allows a cell to engulf another cell, as seen when immune cells called phagocytes devour unwanted debris or bacteria.
