Question: 1 / 1180

Megakaryocytes pinch off to form what?

Erythrocytes

Leukocytes

Platelets

Megakaryocytes are large cells found in bone marrow that produce platelets, which are essential for blood clotting. Erythrocytes are red blood cells responsible for carrying oxygen, while leukocytes are white blood cells that fight infection. Plasma cells are a type of white blood cell responsible for producing antibodies. However, none of these cells are formed by megakaryocytes. Only platelets are formed through the process of megakaryopoiesis, where the megakaryocyte extends its cytoplasm into small protrusions called proplatelets, which then break off to form platelets. Therefore, Option C, platelets, is the correct answer.
