AP BIOLOGY

Detailed explanation-1: -Contrary to their name, white blood cells are colorless but can appear as a very light purple to pink color when examined under a microscope and colored with dye. These extremely tiny cells have a round shape with a distinct center membrane (nucleus).

Detailed explanation-2: -Now, as we have seen that different types of WBC or leukocytes have differently shaped nuclei, we can say that usually, the shape of the nucleus of WBC or leukocytes is irregular.

Detailed explanation-3: -Leukocytes are part of the body’s immune system. They help the body fight infection and other diseases. Types of leukocytes are granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells).

Detailed explanation-4: -The nucleus is most often “U” or kidney bean shaped and the cytoplasm is abundant and light blue (bluer than the micrograph illustrates). These cells leave the blood stream (diapedesis) to become macrophages.
