Final answer:
A microorganism can survive phagocytosis if it possesses a capsule, which acts as a protective shield against phagocytic cells.
Step-by-step explanation:
A microorganism can survive phagocytosis if it possesses a capsule. The capsule is a thick layer of polysaccharides that surrounds the cell wall of some bacteria and helps protect the microorganism from being engulfed and destroyed by phagocytic cells. It acts as a shield, making it difficult for phagocytes to recognize and engulf the microorganism.
