Host cells are living cells in which viruses reproduce. A host cell provides the necessary components for viral replication.
Pathogen: An organism causing disease to its host with detrimental effects similar to how viruses affect host cells.
The process by which cells use oxygen to produce energy from food; this energy helps viruses replicate when they invade host cells.
Lysogenic Cycle: A method employed by certain viruses to replicate within a host cell without killing it immediately.
