17: Prokaryotes (part 2) Quizellenjmchenry2020-07-30T09:08:32-04:00 Please sign up for the course before taking this quiz. The results from a Gram stain tell us about what part of a bacteria?1 The flagella The cytoplasm The nucleus The cell wall Some bacteria have an outermost layer called the capsule. What is it made of?1 polysaccharides proteins phospholipids microtubules The Herxheimer reaction is when your body feels sick because it is processing toxin that are most commonly released by which kind of bacteria when they die?1 Gram positive Gram negative What is the MOST common means of locomotion for a bacteria?1 air bubbles jet-propelled by extruding slime one or more flagella pseudopods Archae bacteria are not suseptible to penicillin or erythromycin.1 True False What does “motility” mean?1 Movement Death Defense Usefulness All bacteria that are Gram negative are bad/pathogens.1 True False How are cilia different from flagella?1 Cilia are found covering the whole of a cell; there is only every one flagellum on a bacterial cell Cilia are made of proteins; flagella are made of carbohydrates. Cilia are used for locomotion; flagella are not. Cilia beat back and forth; flagella spin around in a circle. Which of these is NOT a difference between eubacteria and archae?1 Archae have a nucleus and eubacteria do not. Eubacteria have cell walls made of peptidoglycan, archae do not. Arcahe DNA is wound on spools called histones, while eubacteria DNA is not. Archae has double headed phospholipids in its plasma membrane and eubacteria has a bilayer of single headed phosphopolipids. Until recently, archae and eubacteria used to be classified together as just “bacteria” because they are very similar.1 True False 16: Prokaryotes (part 1) 18: ATP and Glycolysis Back to: 17: Prokaryotes (part 2)
