उत्तर
A matured mammalian erythrocyte lacks a nucleus and mitochondria. The lack of a nucleus
increases the surface area-volume ratio of RBCs, thus increasing the area for oxygen absorption.
Also, the lack of a nucleus reduces the size of the cell, making it easy to flow through the blood
vessels and more cells can be accommodated in a small area.
The lack of mitochondria implies that the cell does not use any oxygen absorbed for respiration,
thus increasing the efficiency of the cell to transport oxygen as all the oxygen absorbed is
transported without any loss.
