Question

what type of cells do platelets come from?
a megakaryocytes
b reticulocytes
c nk cells

Explanation:

Platelets, also known as thrombocytes, are cell fragments. Megakaryocytes are large bone - marrow cells. When megakaryocytes mature, they fragment, and these fragments are the platelets. Reticulocytes are immature red blood cells. NK (Natural Killer) cells are a type of lymphocyte involved in the immune response. Myeloblasts are precursor cells for granulocytes (a type of white blood cell).

A. Megakaryocytes
