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?

Text Solution

Verified by Experts

No, it is not comparable to growth in living organisms, because here growth is due to internal addition of protoplasmic materials by which cells enlarge and divide. However, non-living increase the size, weight etc. due to deposition of materials over the surface.

    How wonderful is the living world! The wide range of the living types is amazing. The extraordinary habitats in which we find living organisms, be it cold mountains, deciduous forests, oceans, fresh water lakes, deserts or hot springs, leave us speechless. The beauty of a galloping horse, or a migrating bird, the valley of flowers or the attacking shark evokes awe and a deep sense of wonder. The ecological conflict and cooperation among members of a population and among populations of a community or even a molecular traffic inside a cell make us deeply reflect on - what indeed is life ? This question has two implicit questions within it. The first is a technical one and seeks answer to what living is as opposed to the non-living, and the second is the philosphical one, and seeks answer to what the purpouse of life is. What is living ? When we try to define 'living', we conventionally look for distinctive characteristics exhibited by living organisms. Growth, reproduction, ability to sense environment and mount a suitable response come to our mind immediately as unique features of living organisms. One can add a few more features like metabolism, ability to self-replicate, self-organize, interact and emergence to this list. Why are the living types amazing ?
