Question

which of the following is not a difference between erythrocytes and leukocytes?
a leukocytes have a nucleus.
b leukocytes are smaller.
c leukocytes have no hemoglobin.
d leukocytes are translucent unless stained.

Explanation:

• Erythrocytes (red blood cells) are smaller than leukocytes (white blood cells). Leukocytes have a nucleus (erythrocytes lose theirs during development), have no hemoglobin (erythrocytes are rich in it), and are translucent unless stained (erythrocytes are red due to hemoglobin).

Answer:

B. Leukocytes are smaller.
