Detailed explanation-1: -Red blood cells are called Erythrocytes. White Blood Cells are called Leucocytes or Leukocytes. WBCs have an irregular shape. Size varies from 6 – 8 µm in diameter.
Detailed explanation-2: -Mature red blood cells do not need to have a nucleus because they have already made all the proteins they will ever need. White blood cells, on the other hand, are actively working to help protect the body from infections and they need to be able to make proteins to do this, and therefore must keep their nuclei.
Detailed explanation-3: -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.
