Endocytosis: Pinocytosis and Phagocytosis:
Entry of large particles inside the cell happens by endocytosis. For this, the cell membrane wraps around the particle to be taken in, and than breaks off a vesicle containing that particle, inside the cell. Pinocytosis is drinking by cell. Large macromolecules are taken in by this process. It occurs in most of the cells. Phagocytosis is eating by the cell. It takes very large things like bacteria or whole cell. Only some cells are capable of phagocytosis. The vesicle formed by endocytosis merge with lysosome to form digestive vesicle. In this, the particle is broken down. Small molecules like amino acids, and glucose thus formed, enter the cytoplasm. And indigestible material is exerted out of the cell by exocytosis.
