SIm plicity Generally, microbes may be considered as fairly simple organisms. Most of the bacteria and protozoa and some of the algae and fungi are single-celled microorganisms, and even the multi celled microbes do not have a great range of cell types. Viruses are not even cells/ just genetic material surrounded by a protein coat, and are incapable of independent existence
