BIOL 203, Microbiology LCC (Final) 100%Accurate There are two cell types - prokaryotic and eukaryotic. List the 7 classes or basic types of microorganisms and identify each as prokaryotic, eukaryotic, both prokaryotic and eukaryotic, or neither. - ANSWER 1. Bacteria- prokaryotic 2. Archaea- prokaryotic 3. Algae- eukaryotic 4. Fungi- eukaryotic 5. Protozoa- eukaryotic 6. Helminthes- eukaryotic 7. Viruses- neither What is a bacterial endospore? Explain how endospore-forming bacteria could cause a scientist to believe in spontaneous generation. - ANSWER A bacterial endospore is an organism that is able to survive in extreme conditions due to their tough structure. Endospore-forming bacteria could cause scientists to believe in spontaneous generation because, they can survive in extreme conditions that would normally kill bacteria. In spontaneous generation, it is said that living things appear from vital forces existing in nonliving or decomposing matter, but there could be bacterial endospore living in that situation without the scientists knowing. Describe how organisms are placed in the Three Domain (Woese-Fox) classification system vs how organisms are placed in the Five Kingdom (Traditional Wittaker) classification system. Which classification system is more useful to a microbiologist and why? - ANSWER Organisms are placed in the Three Domain classification system by using the three main branches, "Bacteria," Archaea," and "Eukarya." They are placed in each domain based on what kind of cell they are (eukaryotic and prokaryotic). Although prokaryotic cells are both Domain Bacteria and Domain Archaea, the members of the Domain Archaea are very different from the ones in Domain Bacteria as they are able to live in severe environments and are also able to produce metabolic byproducts. Organisms are placed in the Five Kingdom classification system by using certain levels tha
