Platelets are derived from which precursor cell?

Explanation:
Platelets are produced in the bone marrow from megakaryocytes. Megakaryocytes are large, polyploid cells of the myeloid lineage that extend long cytoplasmic processes into bone marrow sinusoids; fragments of these processes break off as platelets in a process called thrombopoiesis. This production is mainly regulated by thrombopoietin. Erythroblasts develop into red blood cells, while monocytes and lymphocytes arise from other hematopoietic pathways, not platelets.
