Question

Eukaryotic cells devoid of E.R. are

• A. Liver cells
• B. Kidney cells
• C. Mature leucocytes
• D. Mature erythrocytes

Answer 1

The correct option is D Mature erythrocytes

• The red blood cells in humans lack nucleus, mitochondria and endoplasmic reticulum which allows them to have a biconcave shape that helps in diffusion.
  
• The absence of mitochondria and endoplasmic reticulum allows the RBCs to have more haemoglobin which helps to carry more oxygen molecules.
• Therefore. the RBCs do not divide or replicate like normal cells of the body.
• So, the correct answer is 'Mature erythrocytes'.
