Phagocytosis (from Ancient Greek φαγεῖν (phagein) 'to eat', and κύτος (kytos) 'cell') is the process by which a cell uses its plasma membrane to engulf a large particle (≥ 0.5 μm), giving rise to an internal compartment called the phagosome. It is one type of endocytosis. A cell that performs phagocytosis is called a phagocyte. WebCell walls are an outer structure of cells that are found just beyond the cell membrane.
