B) hemocytoblast, myeloblast, reticulocyte, megakaryocyte, RBC

Question

Quizplus · Accepted Answer

The correct sequence for mature red blood cells is myeloid stem cell, proerythroblast, erythroblast, reticulocyte, and finally RBC. Choice A is incorrect because the erythroblast stage should come before the proerythroblast stage. Choice B is incorrect because it includes myeloblasts, which develop into white blood cells, and megakaryocytes, which produce platelets, and do not directly contribute to the formation of red blood cells. Choice D is incorrect because it includes monoblasts, promonocytes, and band cells, which are all precursors of white blood cells, not red blood cells. Choice E is incorrect because it includes lymphoblasts, which develop into lymphocytes, a type of white blood cell, not red blood cells.
