The formation of pseudopods is a feature specific to the ingestion phase of phagocytosis, where the cell membrane extends to engulf the target particle. Opsonin is a protein that enhances phagocytosis by marking the target particle for recognition by phagocytes. Phagolysosome is the fusion of the phagosome and lysosome, occurring in the maturation phase of phagocytosis. Perforin is a protein used by cytotoxic T cells to puncture holes in the target cell membrane. Residual body is the end product of phagocytosis, containing undigested material that is eventually excreted by the cell.
