Explanation:

Other major groups of microorganisms like bacteria, fungi can also cause human disease, cannot be seen without a microscope, contain genetic material, and some (prokaryotes) lack a nucleus. Viruses are acellular entities that cannot carry out metabolic processes on their own and require a host cell to replicate, which is a unique characteristic not shared by most other major groups of microorganisms.
