Question

Give scientific reason why mature erythrocytes in humans lack nucleus and mitochondria ?​

Answer 1

Reasons :

• A mature erythrocyte lacks nucleus and mitochondria.
• A mature erythrocyte lacks nucleus and mitochondria so as to make a place for the accommodation of more hemoglobin and hence more oxygen molecules.
• Lack of such organelles also provides the peculiar biconcave appearance of RBCs that aids in efficient diffusion.

Answer 2

Answer:

Lack of nucleus and mitochondria in R.B.C. cells helps to accommodate more haemoglobin pigment in its cell for the transport of respiratory gases. Lack of mitochondria help the R.B.C. cells to prevent the self utilization of oxygen for its own needs. Thus, the mature erythrocytes in humans lack nucleus and mitochondria.
