Question

Are all living organisms and human beign's cells made up of atoms. If yes then what atoms and what happens to those atoms when the cell die.

Answer 1

We should always keep this in mind that all the substances are made up of atoms. In case of living cells these atoms have combined to make up various molecules which have combined to form various organelles and ultimately cells. But in non living substances this interaction between atoms and molecules has not taken place and hence they are lifeless. the essential atoms present in the living organsism include, C, N, S, P, Mg, Ca, Mn, Fe H, O etc. Other atoms are also present but in least quantity. When cell dies these atoms are released in the surroundings.
