प्रश्न
The size of the cells of an organism has no relation with the size of its body. Do you agree? Give reason for your answer.
उत्तर
The size of the cells of an organism is not related with the size of its body. This can be understood with the example of an elephant and a rat.
The cells in elephant are not bigger as compared to the cells of small animal like rat. Hence, proving that cells are not related to the size of organism.
However, the size of a cell is related to the function it performs. The nerve cells in both rat and elephant are long and branched and perform the same function of transferring and receiving messages. Thus, helps in coordination of different functions of body parts.
