A CELL IS A LITTLE HUMAN WITHIN
Now let us analyze the cell structure. The cell is basically comprised of a cell membrane, nucleus and cytoplasm ( the liquid that separates membrane and nucleus). The structure of cell constitutes of amino acids. These are huge molecular chains of amines and carbon. The behavior of amino acids depends on how the chains are oriented in space. Eg ( glucose and fructose, these have same molecules in chains but fructose differs in molecular alignment at on carbon center which essentially makes indigestible for humans).
The amino acids contain electron charge clouds which realign themselves when exposed to external charge. Thus when externally controlled on a large scale may result in massive movement , like lifting our hand,walking on our legs and so on...
Thus a cell like a human has its own independent life and works collectively with its neighboring cells like we do and does so in order to improve its chance of living in this world. So we need to understand that there exists no identity of human on his own and he is only a collective response of individual cells that are cooperating with each other for better life.
