Endocytosis-Exocytosis

 * __Endocytosis and Exocytosis__

[|**VIDEO**]


 * Endocytosis is the movement of materials into a cell via membranous vesicles. Exocytosis is the movement of materials out of a cell via membranous vesicles.
 * Endocytosis:
 * three types of endocytosis: pinocytosis, phagosytosis, and receptor mediated endocytosis
 * cell membrane folds and forms a small pouch. The pouch slowly tears off from the cell membrane and becomes a vesicle.
 * Exocytosis is the reverse of endocytosis
 * materials leave the cell without passing through the membrane as their own individual molecule.
 * active transport process
 * Mandatory for intracellular digestion.
 * food particles enter the cell through endocytosis in a vacuole
 * Exocytosis moves particles from the cytoplasm of the cell wall to the exterior of the cell.
