Question

Which of the following cells do NOT contain a nucleus?
A) neutrophils
B) red blood cells
C) eosinophils
D) monocytes

Accepted Answer

Red blood cells, also known as erythrocytes, are the only cells listed that do not contain a nucleus. They lose their nucleus during maturation in order to make more room to carry oxygen. Neutrophils, eosinophils, and monocytes are all types of white blood cells that contain a nucleus.
