Endocytosis Endocytosis is a type of active transport that moves particles, such as large molecules, parts of cells, and even whole cells, into a cell There are different variations of endocytosis, but all share a common characteristic the plasma membrane of the cell invaginates, forming a pocket around the target particleThe key difference between endocytosis and exocytosis is that endocytosis brings substances into the cell while exocytosis transports substances to the outside of the cell A cell has a cell membrane that acts as a barrier between the cell interior and the external environment Therefore, having such a membrane, cells need some kind of transportation mechanism to connect with the Endocytosis Step 1 The cell comes into contact with a particle Endocytosis Step 2 The cell membrane begins to wrap around the partile Endocytosis Step 3 Once the particle is completely surrounded, a vesicle pinches off Exocytosis Step 1
