Viruses need any kind of cell. Some have "favorites" like white blood cells (HIV).
the virus needs the host to reproduce!! : )
yes a virus need host cell to repriduce becouse it lack enzyme system
virus is obligate patogen it only can reproduce by killing the host cells.
they arent the same a virus is technically not condidered living because it does not have all the proper organells but it can count as a protist or a parasite which needs to attach itself to a host to live and reproduce that is another reason viruses are not like cellls because they cannot reproduce on their own they need a host and once they infect the host they reproduce the same virus and so on but anyway a cell is like a virus for a number of reasons just GOOGLE it retard have a nice day
To continue to replicate and exist, a flu virus must be in a host animal's cells. They can be grown in cultures (and eggs) for creating vaccines, but need a living host for long term activity and to "live".
they can not reproduce without a host cell .
Protein synthesis is important for viruses because the virus forces the host cell to make proteins that the cell does not need, but the virus does to repoduce. Protein synthesis is important for cells because the proteins are essential for all cellular activites.
To reproduce
The virus attempts to take over the host cell's DNA, and if successful, when the host cells divide via mitosis, instead of making copies of a healthy cell, the system produces new copies of the virus infected cell, which leads to an infection.
It depends on the kind of Bacteria you are talking about. Most do not depend on a host and live on their own. Some, such as E. coli can live outside a host at least for some time. A few are entirely dependent on a host.
Nope - they can reproduce all by themselves - by dividing.
What we need to understand is, viruses do not have its own synthetic machinery such as ribosomes to make proteins. Hence they are completely dependent on the host synthetic machinery for their replication. Virus infects the host cells, integrate its genetic material with the host to produce progeny viral particles.
