Basically because it does not have the things required to BE a cell, which is considered to be an organism. A virus is not considered an organism. The virus has a core of RNA or DNA which is surrounded by a protein coat. Unlike cells that can either go through mitosis or binary fission, viruses cannot replicate itself unless it is in a host cell.

Viruses are not living because they require a host cell. All cells are living. Viruses are primarily a protein coat for protection and within is RNA or DNA. They are incredibly much smaller.

∙ 13y agoA virus isn't considered living because it isn't made up of cells and needs other cellular organisms to reproduce. It has its own set of DNA, but has no way of producing its own proteins and reproducing.

∙ 13y agoWell, all viruses are not cells! Where did you get that question?
Wiki User
∙ 13y agoBecause they are just a piece of RNA or DNA that injects its RNA or DNA into a host to produce more.

Is mitochondria a virus?
Virus are not considered as living or dead.They do not have organells.
Which component of a virus is lacking in a cell?
Both a living cell and a virus contain nucleic acid. The virus has a capsid, whereas a living cell does not.
Why is a virus considered a none living thing?
They have no metabolism, no cellular structure, and can not reproduce without a host cell. They are considered to straddle the line between "life" and "nonlife".
What is outside a living cell virus?
faeces
Why is an isolated virus not considered living?
They are not alive. They are like cockle burrs that "grab" hold of your clothing or a dog's coat. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own.
What cell comes in a fundamental living matter and come in two forms?
DNA is the fundamental living matter. A virus, considered to be a living matter consists of core of DNA. When this virus invades a Bacterial cell, it forms the Bacteriophase.DNA is the fundamental living matter. A virus, considered to be a living matter consists of core of DNA.

What group does virus belong to?
Be more specific? Viruses can be considered pathogens, but they are not considered living because they do not obey the cell theory.
What do a virus and a living cell have in common?
Viruses cannot reproduce. They use a living cell to replicate themselves. When a virus infects a living cell, it injects its genetic material (DNA or RNA) into the cell. The virus' genetic material takes control of the cell and turns it into a virus factory. The cell does nothing but manufacture and assemble virus parts until eventually the cell ruptures and the new viruses erupt and go on to infect more cells.
What would happen to a virus that never came in contact with a living cell-?
Since a virus can only replicate on a living cell, host cell, it wouldn't be able to reproduce.
How does a host living cell face with an enemy virus?
A virus and a cell have to have matching "docking" proteins for the virus to invade. Otherwise the virus is blocked.
Why is a virus considered a none living thing?
They have no metabolism, no cellular structure, and can not reproduce without a host cell. They are considered to straddle the line between "life" and "nonlife".
What provides energy for an virus?
A virus does not have a metabolism. To reproduce, a virus takes control of a living cell, forcing the cell to make copies of the virus. All energy is provided by the cell.
Is Ebola virus a living or non-living organisim?
Virus cannot considered living. They lack cellular organization
