AThe erythrocytes
BThe platelets
CThe reticulocytes
DThe leukocytes
Answer & Solution
Correct answer: D. The leukocytes
1. Mature erythrocytes have extruded their nucleus and most organelles, so they are not complete cells.
2. Platelets are only fragments of megakaryocyte cytoplasm, so they are not cells at all.
3. Leukocytes are therefore the only formed elements that are complete cells with a nucleus and organelles.
4. The reticulocyte still holds remnants of organelles but is already anucleate, so it does not qualify either.
