Platelets are produced from which cell type?

Explanation:
Platelets come from megakaryocytes in the bone marrow through a process called thrombopoiesis. Mature megakaryocytes extend long cytoplasmic processes into nearby blood vessels, and their cytoplasm fragments into small, anucleate platelets that enter the circulation. Thrombopoietin drives this maturation and production. This differs from erythrocytes (from erythroid precursors), lymphocytes (from lymphoid precursors), and monocytes (from other myeloid precursors), making megakaryocytes the source of platelets.
