Fig.1: Monocyte
Explanation of Solution
In the immune system, monocytes are one of the crucial white blood cells. Monocytes are amoeboid in structure and possess non-granulated cytoplasm; hence, they are termed as agranulocytes. They differentiate into macrophages. If an infection or tissue damage happens, the monocytes leave the blood and reach the affected area (tissue) and undergo a sequence of changes to become macrophages. They are also involved in the tissue repair mechanism.
