Destroy microbes by producing perforins
WebNormally a large number of food-poisoning bacteria must be present to cause illness. Therefore, illness can be prevented by (1) controlling the initial number of bacteria … WebSolution Verified by Toppr Correct option is C) Phagocytes have the ability to phagocytose or kill foreign cells and particles like pathogens by ingesting them. Many blood cells have this function, including monocytes, neutrophils and macrophages. Basophils do not have phagocytic activity. Thus, the correct answer is 'Basophil.'
