Detailed explanation-1: -Viruses are obligate parasites. They cannot reproduce outside living cells. Therefore, they are considered obligate intracellular parasites. They infect a host cell to use its genetic machinery to produce energy, synthesize proteins, and replicate.
Detailed explanation-2: -An obligate parasite is a parasitic organism that is not able to complete its life cycle without exploitation of suitable host. They can grow within a living cell only. They must live parasitically on the host and they die when the host dies.
Detailed explanation-3: -Viruses are obligate parasites in that they can only replicate within a living host cell.
Detailed explanation-4: -We can say that they are powerless to achieve life procedures external to the living cells of an organism. Outside the living cells, the viruses perform as unassuming substances. Thus, viruses are called an obligate intracellular parasite.
