Viruses are essentially parasites at the lowest level of life. They are incapable of reproducing their RNA without entering into a cell. There, it "hoodwinks" the cell into reproducing their RNA from which other viral particles can be formed.

Virus is a bundle of genetic material (DNA or RNA). It is on the border line of living and non-living organisms. It behaves as if a non-living organism when outside, but as soon as it enters the body of a host it behaves as a living organism.It has very few bio-chemical pathways of its own. It uses the machinery of the host cell to carry out its bio-chemical reactions.It is not cellular. The host cell may be a plant ,an animal or even a Bacterium.

Virus is a type of micro-organism which causes diseases.The difference between Virus & Living Organism is that Virus shows characteristics of life only when they are inside living cells,But shows non-living attributes when they are outside.

Viruses are such organisms which can neither be said to be living nor non living. They remain inactive unless they get a favourable condition and they flourish when they get one.They are highly specific (i.e. they attack only one kind of host).
The difference between the viruses and the other living organisms is as follows :-
1.viruses are very small and can only be seen through an electron microscope.
2.they arenon cellular but others are cellular(they consist of cells).
3.viruses have no metabolism but others have metabolism.
4.viruses take no food by any method where others do.
5.they do not grow and do not divide where as others do.
6.they can be crystallised.
7.other organisms reproduce themselves but viruses command the host to produce more of their kind.
8.they all produce diseases.

Viruses are obligate intracellular parasites. They lack any sort of energy synthesizing equipment so they can't synthesize any proteins for growth or maintenance or anything like that. They carry with them only what genes are necessary to replicate once it has entered the host cell. They are not alive, but once they inhabit a host cell, viruses become alive. Living organisms are alive because they are able to synthesize their own energy, maintain protein structure without anything else.

viruses show the property of both living and non-living.these are inactive in an open environment while active in a cell and can reproduce themself.while maximum organism are living and can live individually.deases causes by viruses cannot easily cured.bcoz these live in the cell and destroying them means destroying the cell which can cause death.while other organism live outside and indivisually and so they can be easily cured that is why aids and cancer are very difficult to cure.these are the basic difference.

Virus: Infectious particle consisting of a core of nucleic acid (i.e. DNA or RNA), enclosed in a protein shell. Viruses are acellular (i.e. they are not living or dead cells like normal plant/animal cells). They can function and reproduce only if they can enter a living cell to use the cell's system to replicate themselves. In the process they may disrupt or alter the host cell's DNA.

The ultimate purpose of life is reproduction, so when compared between viruses and living organisms, we come to a result that living organisms have their own cellular and metabolic machinary whereas viruses don't have and depend upon the host.

Virus is fast replicating while other living organisms reproduce slowly.

virus- they r non-living outside the host
they may hav dna/rna
requires a living media to grow
they do not have cell oranelles
sexual mode of reproduction is absent
only proteins r seen
