host cells!

true

Viruses that enter a cell do not die. A virus cannot reproduce on its own so it needs to find a cell in which to live. After the virus is done reproducing, most host cells die.

viruses can not reproduce without the help of a living cell(host).they remain inert or dead(in-active) when they are in free environment or outside the body(host).when they enter the living cell or in some cases insert their nucleic acid into the host,it takes over the host's biosynthetic machinery and forces it to reproduce essential viral components and after proper assembly the cell burst and viruses leave the cell to infect other cells

Host cells of viruses include human and other animals, and plants and fungi. Also bacteria and protozoa and algae are host cells of viruses.
