Quiz: Types Of Microorganisms! Trivia Questions

There are different types of microorganisms; some are unicellular, multicellular, or cell clusters. According to our previous classes, we learned that there are six major types of microorganisms and they are different from each other some can be harmless while others are very harmful to humans, animals or any of its hosts. Take this test and see if you know them all!
