Question

iv) Which of the following is without nucleus? a) RBC b) Neutrophil c) Lymphocytes d) Basophils.​

Answer 1

The blood cells without nuclei are erythrocytes or Red blood cells.

Answer 2

a) RBC is without a nucleus.

• The function of red blood cells or erythrocytes is to transport oxygen to various organs of the body.
• To minimise the energy requirements and accommodate oxygen molecules, it lacks organelles and a nucleus.
• Moreover, the absence of organelles is responsible for its biconcave shop which helps in diffusion.
• Neutrophils, lymphocytes and basophils are white blood cells that fight infections.
