Final answer:
2. Chemotaxis is the type of cell movement involved in cancer cell spread, wound healing, and blood clotting, and macrophages are the cells that perform phagocytosis.
Step-by-step explanation:
The type of cell movement involved in the spreading of cancer cells, wound healing, and blood clotting is chemotaxis. Chemotaxis is the movement of cells, such as phagocytes, toward a higher concentration of a chemical stimulus, often signaling injury or infection. Phagocytes destroy ingested bacteria through the process of phagocytosis, which involves engulfing the bacterium, forming a phagolysosome where the bacterium is killed and digested, and then expelling the undigested remains.
When asking which of the following cells is phagocytic, the answer is b. macrophage. Macrophages are key players in the immune response and are able to ingest and break down pathogens and cellular debris.
