Chapter 1: Mastering Microbiology The Early Years of Microbiology Leeuwenhoek’s observations of microbes introduced most types of microorganisms to the world. His discoveries were names and classified by Linnaeus in his taxonomic system. Small prokaryotes- bacteria and archaea, live in a variety of communities and in most habitats. Even though some cause disease, most are beneficial. Relatively large microscopic eukaryotic fungi include molds and yeasts. Animal-like protozoa are single-celled eukaryotes. Some cause disease. Plantlike eukaryotic algae are important providers of oxygen, serve as food for many marine animals, and make chemicals used in microbiological growth media. Parasitic worms, the largest organisms studied by microbiologists, are often visible without a microscope, although their immature stages are microscopic. Viruses, the smallest microbes, are so small they can be seen only with an electron microscope. All are ACELLULAR. Bacteria and Archaea produce asexually Molds produce sexual and asexually spores, are multicellular Penicillium chrysogenum is a mold that produces penicillin Yeasts, unicellular, produce asexually by budding.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
