Question

multiple choice question
what are megakaryocytes?

large antigen - antibody complexes
the largest of the white blood cells
gigantic bone marrow cells that produce platelets
precursor cells that produce all types of granulocytes

Explanation:

To determine the correct answer, we analyze each option:

• "Large antigen - antibody complexes" is incorrect as megakaryocytes are cells, not complexes.
• "The largest of the white blood cells" is incorrect. The largest white blood cells are macrophages or monocytes, not megakaryocytes.
• "Gigantic bone marrow cells that produce platelets" is correct. Megakaryocytes are large cells in the bone marrow that fragment to form platelets.
• "Precursor cells that produce all types of granulocytes" is incorrect. The precursor cells for granulocytes are myeloblasts, not megakaryocytes.

Answer:

C. Gigantic bone marrow cells that produce platelets
