Tap to reveal answer

Answer

Bacteria are prokaryotic organisms and are considered alive. Bacteria can survive and reproduce independent of a host (consider a colony of bacteria cells growing in a Petri dish). Though they do not have membrane-bound organelles, like a nucleus or mitochondria, bacterial cells do have DNA and are still able to produce cellular energy.

This question confuses many properties of viruses with those of bacteria. Viruses are not generally considered alive and require a host cell in order to replicate.
