Viruses are not classified as living things because they do not have the properties of living things such as reproductive function.
They need to have a host for their genetic material. On the other hand, all living cells can reproduce if they are signalled.
They also do not have cellular structure
They do not have their own metabolism

Which organism is considered an exception to the cell theory?
Skeletal muscles and some fungal hyphae are not divided into cells but have a multinucleate cytoplasm. Some biologists consider unicellular organisms to be acellular
Why are viruses considered an exception to the cell theory?
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 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.
Why is the cell invaded by the virus called a host cell?
A cell invaded by a virus is known as the 'host cell', as it 'hosted' the virus with shelter and food.
What happens when a virus enters a plant cell?
The cell becomes a virus breeding machine the virus takes over the cell and uses it to make more viruses
What does the cell theory not apply too?
Not to virus because they are not life forms!

Can human genetic engineering be done on adults?
In theory it could. A virus goes into a cell an replaces its DNA to make that cell produce more virus. So in theory we could make a viral infection that would go into the cells and change the DNA, it would be very completed though.
Where can I get a Drawing of a virus cell?
No where. A virus is not a cell.
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 does a cell and virus have in common?
What a cell and a virus have in common is the RNA or DNA. The virus can be either a RNA virus or a DNA virus.
Which is smaller a cell or virus?
A virus.
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.
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.
Why is the virus eukaryote cell?
It has no nucleus, though technically a virus is not a cell at all.
The cell a virus lives on or in is called?
A virus will replicate within a host cell.
