This mode of transport does not require substances to pass through the membrane structure, but transports substances contained in membrane covered vesicles. In endocytosis, extracellular material is absorbed by being packaged into vesicles at the cell membrane. The vesicles are formed by invagination of the membrane. An equivalent process in reverse is exocytosis, which allows the cell to export intracellular substances or debris (Figure PG. 18).
