In the formation of platelets, the megakaryocyte:
1. Breaks into pieces called platelets.
2. Is a part of the formation of any cell type.
3. Is necessary for RBC formation.
4. Does not release platelets.
Breaks into pieces called platelets.
Rationale: Megakaryocytes do break into pieces called platelets as part of the stem-cell-to-thrombocyte formation process. The stem cell is the precursor cell of all blood components (red blood cells, white blood cells, and platelets.) Megakaryocytes are not responsible for RBC formation.
