Do you consider a virus living or non-living organism? In middle school, I was taught that a virus was the smallest living organism. However, I see viruses as packages of genes coated in protein and that they are inert on their own. I think of viruses as stuck in a "Twilight Zone" between living and non living. I don't think that viruses are true living organisms because they do not grow by dividing, generate energy, creating protein, etc. Yet, some scientists believe they are living because they contain genes necessary for their replication. And there are some bacteria that are like viruses, unable to reproduce outside a host cell, such as Chlamydia or Rickettsia that are classified as living organisms. But they have the same limitations as viruses. p.s. I think there was a similar topic for some research paper that was posted in 2009. I can't seem to find it.
