Question

multiple choice question
dendritic cells engulf foreign matter by ______.

○ phagocytosis
○ receptor - mediated endocytosis
○ exocytosis
○ pinocytosis

Explanation:

Dendritic cells are antigen - presenting cells that engulf large particles (like foreign matter) through phagocytosis. Receptor - mediated endocytosis is for specific molecules, exocytosis is for releasing substances out of the cell, and pinocytosis is for taking in fluid and small solutes. So the correct process for dendritic cells to engulf foreign matter is phagocytosis.

Answer:

A. phagocytosis
