Question

Which of the following is non nucleated?
(1) Monocyte
(2) Lymphocyte
(3) Platelet
(4) Neutrophil​

Answer 1

Answer:

3 : Platelet

Monocytes are the largest of all leukocytes and form a part of the innate immune system. They have bean-shaped nuclei.

Red blood corpuscles or erythrocytes, rich in haemoglobin carry oxygen to different tissues. They lack nucleus at maturity.

Neutrophils are phagocytic leukocytes contributing to innate immunity. They have a nucleus divided into 25 lobes.

Platelets are devoid of the nucleus. They are fragments of cytoplasm which are derived from the megakaryocyte of the bone marrow. Hence they are not considered as true cells

Answer 2

3) platelets do not contain nucleus.
