In innate immunity, white blood cells engulf and internalize bacteria using which cellular process?
A
Diffusion
B
Phagocytosis
C
Osmosis
D
Binary fission
Verified step by step guidance1
Identify the key function described: white blood cells engulfing and internalizing bacteria, which involves active cellular uptake.
Recall that diffusion and osmosis are passive transport processes involving movement of molecules across membranes, not engulfing whole cells or particles.
Understand that binary fission is a method of bacterial reproduction, not a process used by white blood cells.
Recognize that the process where cells engulf large particles like bacteria is called phagocytosis, a form of endocytosis specific to solid particles.
Conclude that the correct cellular process used by white blood cells to engulf bacteria is phagocytosis.
