Monocytes typically have:

Monocytes typically have:

• A. Lobular nuclei
• B. Segmented nuclei
• C. Band-shaped nuclei
• D. No nuclei

Answer: (A)

Monocytes show a nucleus that is large and irregular, often indented or kidney-shaped. This gives a lobulated or irregular appearance rather than a smooth, round nucleus. That distinct single, oddly shaped nucleus helps differentiate them from other white cells: neutrophils have multi-lobed segmented nuclei, band neutrophils have a crescent or band-shaped nucleus, and lymphocytes have a small, round, dense nucleus with little cytoplasm. Since monocytes are nucleated, the idea of “no nuclei” doesn’t fit. So the hallmark feature you’d expect is a lobular (irregular, indented) nucleus.
