Why viruses are difficult to classify as living organisms?

Are viruses general or specific to the cells that they infect?
viruses are specific to the cells they infect called host cells
Is genetic material found in both cells and viruses?
Yes, both viruses and cells have DNA.
Are viruses made up of tissues?
No, tissues are made up of cells and viruses are not even cells.
Why do you classify viruses as obligatory intracellular parasite?
Viruses need living cells to produce more viruses. They are obliged to use living cells.
Are viruses made of a cell or cells?
well viruses are caused by bacteria and bacteria are cells. so yes
Are viruses made out of a cell or cells?
well viruses are caused by bacteria and bacteria are cells. so yes
When body cells are attacked by viruses they produce what?
INTERFERON is a substance produced by body cells when they are attacked by viruses.
Does cells have viruses?
cells are not made with viruses unless the virus gets into the cell itself. The viruses get into the cell and the virus will spread killing off whatever it can ;)
Viruses are single celled organisms?
No. Viruses are not cells. They invade cells to get the materials to copy their DNA. Many people do not consider viruses to be truly alive.
