MICROBIOLOGY: EXAM 1 WITH COMPLETE SOLUTIONS 100% Microorganisms - correct answer Cannot be seen with the naked eye. All microorganisms require a microscope to be seen. Microorganisms include yeast, protozoan, bacteria, and viruses. Mushrooms are NOT microorganisms because they can be seen with the unaided eye. They are grouped in with the study of microbiology because they are part of the fungi family. The study of fungi (molds, yeast, and mushrooms) is called mycology. Pathogens - correct...
