Detailed explanation-1: -Most biologists say no. Viruses are not made out of cells, they can’t keep themselves in a stable state, they don’t grow, and they can’t make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
Detailed explanation-2: -This is because viruses do not have the cellular machinery that is required to multiply, hence they hijack a living cell. Another aspect that makes viruses lie on the border between the living and the non-living is their ability to be crystallized.
Detailed explanation-3: -Viruses are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.
Detailed explanation-4: -They do not possess ribosomes and cannot independently form proteins from molecules of messenger RNA. Because of these limitations, viruses can replicate only within a living host cell. Therefore, viruses are obligate intracellular parasites. According to a stringent definition of life, they are nonliving.
Detailed explanation-5: -They don’t have cytoplasm or cellular organelles, and they’re not cells. Within the infected host cell, new viruses are produced and assembled. The viruses are inactive outside of the host. They are unable to reproduce or develop outside of the host cell. More items
