Question : 26
Total: 36
A mature mammalian erythrocyte lacks nucleus and mitochondria but is efficient in its functioning. Explain by giving suitable reasons.
Solution:
Loss of nucleus makes red blood cells biconcave thus increasing their surface area volume ratio for absorbing more oxygen.
Due to loss of mitochondria, no cellular respiration occurs in red blood cells so oxygen absorbed from lungs, is transported and delivered to the tissues unconsumed.
