Quizplus · Accepted Answer

Viruses are not considered living organisms by some biologists as they do not exhibit all the characteristics of life when isolated, such as being unable to reproduce or maintain homeostasis on their own. Therefore, it is hard to apply present criteria for life to viruses when they are in an isolated state. Viruses are not considered alive by some definitions of life, as they cannot replicate without a host cell and do not exhibit all the characteristics of life when isolated. Thus, it is difficult to apply present criteria for life to a virus when it is isolated.
