We live in an world that provided a stage for us for our existence. Us!!!! what are we? We are system. A system is composition of various parts made of materials. System have an input and a desired output. Yes I be precise we are a system made of various parts called organs. Hmm!  various organs like Heart, Skin, muslces, Eyes, Brains etc. But What are the things with which these organs are made of. Yes the Cells. Cells in itself is a complete system and live without the help of any other cell if the favourable conditions exists in surroundings. A single cell species ameba parameciaums are common examples.

This is the microsopic view showing the amooeba.

But each of these cells what we can call life unit is made of the cluster of compounds. cluster of compounds are made of compounds or molecules and molecules are made of atomes or basic elements. these atoms are made of the fundamental particles like electron proton neutron. and these particles are made of the quarks. At the time we know upto the level of quarks only. Quarks first discovered at SLAC in 1968 until then 6 types of quarks have been discovered.

we have broken ourselves and all the living thing into the zero level particles. What about other non living things around us. Yes they all are made of the same fundamental particles So principly we are made of the non living materials those form a system that we call a living thing.

Which things we should call a living thing. Any thing having following property called a living thing.

1.  It have metabolism. ::: A process to generate energy to carryout the basic life processes.
2. Reproduction           :::: generates its copy  or give birth
