Ask AI: Why are viruses categorized as non living things

Viruses are considered non-living because they cannot reproduce, metabolize, or carry out any other life processes without a host cell. They are essentially a small piece of genetic material (DNA or RNA) enclosed in a protein coat. Viruses cannot function independently and require a host cell to replicate themselves. Once inside a host cell, they take over the cell's machinery to produce more virus particles, but they cannot do so without the host. Thus, viruses do not meet the traditional criteria for life, which includes the ability to grow, reproduce, maintain homeostasis, and respond to stimuli.
