Detailed explanation-1: -Viruses do not carry out respiration. They also do not grow or reproduce on their own. A virus needs a living cell in order to reproduce. The living cell in which the virus reproduces is called a host cell.
Detailed explanation-2: -Viruses cannot replicate on their own, but rather depend on their host cell’s protein synthesis pathways to reproduce. This typically occurs by the virus inserting its genetic material in host cells, co-opting the proteins to create viral replicates, until the cell bursts from the high volume of new viral particles.
Detailed explanation-3: -They are incapable of surviving independently and require a host to conduct their life processes. They are parasitic in nature and require the host to provide energy and replicate.
