Exocytosis. Exocytosis is the reverse of endocytosis. Quatities of material are expelled from the cell without ever passing through the membrane as individual molecules. By using the processes of endocytosis and exocytosis, some specialized types of cells move large amounts of bulk material into and out of themselves.ndocystosis, is a general term for the process whereby very large particles of material are wrapped with plasma membrane and moved into the cell in the form of vesicles or vacuoles.
Endocytosis is the opposite of exocytosis: the cell membrane engulfs a substance the cell needs to import and then pinches off into a vesicle that is inside the cell. There are two kinds of endocytosis: in phagocytosis the cell takes in large solid food particles that it then digests.
