A ball of snow when rolled over snow increases in mass, volume and size. Is this comparable to growth as seen in living organisms? Why?
When the iceball is rolled its size increases, it happens due to extrinsic growth by the deposition of the same material.
But in case of living beings intrinsic growth occurs. In unicellular living organisms reproduction takes place by splitting of parent cell into two daughter cells i.e. binary fission. Hence reproduction is equivalent to growth.
It can be concluded that growth in case of ice ball is completely different from the growth which occurs in case of living organisms.
