Detailed explanation-1: -So were they ever alive? 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: -Viruses are considered as something between living and non-living because they do not grow or reproduce by themselves. This makes them non-living.
Detailed explanation-3: -Although viruses are not classified as living things, they share two important traits with living things. They have genetic material, and they can evolve. This is why the classification of viruses has been controversial. It calls into question just what it means to be alive.
Detailed explanation-4: -Viruses lack cellular machinery and hence do not show any characteristics of life until they enter a living body/host and use the host cell to multiply.
