A virus "replicates" [the term often heard in place of "reproduces"] inside a host cell with the process called the Lytic Cycle. The details of the steps of the Lytic Cycle are in the related questions below in the Related Questions section.
Basically, once the virus has found a suitable host that is made up of the type of host cells that its virus type uses (i.e., plant, animal ~ including insects to humans, or bacteria), it attaches to the host. Then the virus implants the "key" to its genetic makeup into the cell. When this DNA "key" (or RNA in some viruses) of the virus is inserted into cells of a host, it allows the cells to be hijacked and, at the appropriate time for that particular virus, it instructs the host to make more virus particles. The virus can either lie dormant, such as in some cases of the HIV/AIDS virus, or immediately become active and command the host cell to start the replication processes.
If the virus becomes active, it can then turn the host cell into a 'factory' for making more viruses. The result usually, but not always, is that the host becomes ill because the cells are no longer functioning as they should for the host while working on the job of the replication. With each cycle of replication, the virus particles can invade even more and more cells until the host's immune system (or other defense) can catch up to kill the invader.

What are reasons viruses are considered non living?
Two very important reasons are growth and reproduction. Viruses do not have a way of converting potential energy, or photonic energy, into useful forms; no metabolism. Viruses can not reproduce on their own and must hijack a cell's reproductive machinery to reproduce themselves.
Are Viruses able to reproduce without using other organisms?
viruses are dormant when they are not inside a living cell. that means they don't have living characteristics when outside a living cell. they only reproduce when they are inside a living cell.
Do viruses only reproduce inside living things?
A Virus must invade a host cell in order to reproduce. What people commonly mix up with them is bacteria which has no need to
What is a male virus called?
There are no male and female viruses. Viruses do not reproduce sexually and so do not have gender.
What is a difference between bacteria and viruses shows that bacteria are living organisms and viruses are nit?
Part of the definition of a living thing is that it can reproduce itself, which a virus can't do. Bacteria reproduce like any other cellular organism: by cellular division. Viruses, however, can not reproduce themselves. Instead, they infect other cells and force those to make more viruses.
These pathogens cannot reproduce on their own and they must invade other cells to multiply?
Viruses
Can viruses can reproduce by themselves?
No. Viruses must invade a host cell and hijack its resources to replicate itself.
Can viruses reproduce by themselves?
No. Viruses must invade a host cell and hijack its resources to replicate itself.
Viruses must reproduce in a cell because they lack organelles needed to duplicate viral components?
. Viruses must reproduce in a host cell because they lack organelles needed to duplicate viral components. True or false

Why scientist believe that virus are not living organisms?
viruses do not grow, and viruses do not respond to changes in their environment. Therefore, viruses are not living organisms. All living things reproduce, but Viruses need living cells to reproduce because Viruses cannot reproduce by themselves.
Which microorganisns cannot multiply on their own?
Viruses cannot reproduce on their own. They must invade and infect other cells in order to be able to reproduce.
Are Viruses able to reproduce without using other organisms?
viruses are dormant when they are not inside a living cell. that means they don't have living characteristics when outside a living cell. they only reproduce when they are inside a living cell.
Does virus reproduce artificially?
Viruses must be produced in a host cell. They can be produced in vitro (in glass) if there are host cells in there first.
Do viruses only reproduce inside living things?
A Virus must invade a host cell in order to reproduce. What people commonly mix up with them is bacteria which has no need to
What to viruses reproduce?
a host Cell
What is a difference between bacteria and viruses that shows that bacteria are living organims and viruses are not?
Bacteria metabolize ingested nutrients. Viruses do not do this. Bacteria reproduce by fusion. A virus needs a host to reproduce. Bacteria exchange gases with the environment. A virus does do this. A bacteria is motile in many cases. Flagella. Viruses must depend on the current in solution. As you see viruses do not have any of the markers of living organisms, but some biologists do not fully agree that viruses are not a sort of living organism.
