True or False: A virus requires live cells, such as those in the human body, to reproduce.

The statement is true because viruses are obligate intracellular parasites, meaning they cannot reproduce on their own and must infect a host cell to replicate. When a virus enters a living cell, it hijacks the cell's machinery to produce new virus particles. This dependence on living cells is a fundamental characteristic of viruses. They rely on the cellular processes of the host to create the components necessary for new virus formation and to propagate themselves. Therefore, the requirement of live cells for a virus to reproduce is an essential aspect of what distinguishes viruses from other microorganisms.
