Detailed explanation-1: -All white blood cells have nuclei, which distinguishes them from the other blood cells, the anucleated red blood cells (RBCs) and platelets. The different white blood cells are usually classified by cell lineage (myeloid cells or lymphoid cells). White blood cells are part of the body’s immune system.
Detailed explanation-2: -The absence of a nucleus is an adaptation of the red blood cell for its role. It allows the red blood cell to contain more hemoglobin and, therefore, carry more oxygen molecules. It also allows the cell to have its distinctive bi-concave shape which aids diffusion.
Detailed explanation-3: -White blood cells or leukocytes are mainly composed of cellular organelles, including the nucleus, nuclear lobes, cytoplasm, Lysosomes, mitochondria, Golgi apparatus, and vesicles.
