Q7.Which of the following cells are round and biconcave in shape?
Solution
Red blood cells (RBC_S) or erythrocytes are the most abundant of all the cells in blood. They are devoid of nucleus in most of the mammals and are round or biconcave in shape. It is biconcave because such a shape has increase surface area (for O_2transfer) and allows easy squeezability of the RBC_S through the blood vessels.
