Question

Compare and contrast the traits of viruses and bacteria. Why do most scientists argue that a virus is not considered a living thing? Explain your answer in 3–5 sentences. Please make your answer simple, coherent, and intended for 9th grade.

Answer 1

Viruses and bacteria are both types of microorganisms, but they have key differences. Bacteria are single-celled living organisms that can survive on their own, reproduce, and carry out metabolic processes. In contrast, viruses are much smaller and cannot live independently; they need a host cell to reproduce and don’t have their own metabolism. Most scientists argue that viruses are not considered living things because they cannot grow, reproduce, or carry out any life processes without invading a host organism. This dependency on a host is a major reason they are classified differently than bacteria.
