Name the blood cells in which nucleus is absent?

A. Lymphocytes
B. Blood Platelets
C. Monocytes
D. Eosinophil

Correct Answer:

Option B – Blood Platelets

Explanation

Like red cells, platelets (thrombocytes) have no nucleus. However, unlike red cells that originate in the marrow as nucleated cells and lose their nucleus, platelets are produced by budding off from a giant multinucleated marrow cell called a megakaryocyte.
