Viruses and bacteria differ significantly in their structure and function. Bacteria are single-celled organisms with a complex cell structure, including cellular membranes and the ability to reproduce independently through binary fission. In contrast, viruses are much smaller and lack cellular structure; they cannot reproduce on their own and must hijack a host cell's machinery to replicate. Most scientists argue that viruses are not considered living organisms because they do not have metabolic processes or the ability to grow and reproduce independently, key characteristics that define life. This reliance on host cells for replication and function underscores their classification as entities existing at the edge of life.
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.(4 points)
