Endocytosis is a process involving the bulk transport of materials into cells by membranes.
It occurs by infolding or extension of the cell surface membrane to form a vesicle or the vacuole.
Endocytosis generally occurs by an infolding or extension of the cell surface membrane to form a vesicle.
It is generally of two types, namely pinocytosis (cell drinking) and phagocytosis (cell eating).
Pinocytosis is referred to as a process by which the cell takes in the fluids along with dissolved small molecules. Pinocytosis is an example of endocytosis and is commonly seen in amoeba.
