Document Summary
Science of microorganisms (very small, mostly unicellular organisms) Examines how microbes interact with humans, with food, and how they can be used by humans. Discipline is just over a century old. Given rise to molecular biology and biotechnology. Organisms that are too small to see with the unaided eye. Consist of single cell and include bacteria, archaeans, fungi, protozoa, and algae. Viruses not living, are microscopic, utilize biological molecules and cellular machinery (from host) to replicate, cause infectious diseases like microorganisms. Viruses not microorganisms, refer to as microbes. Marcroorganisms large enough to be seen by an unaided eye. No optical instrument needed such as microscopes. A microorganism, especially a bacterium causing disease or fermentation. Microbiology study of microbes (include microorganisms and viruses) Some microbes cause crops to fail, while others provide essential nitrogen to plant roots through symbiotic relationships. Some microbes cause food to rot, while others carry out fermentation to produce yogurt, wine, beer, and other food beverages.
