What does “motility” mean?1 Movement Usefulness Defense Death 3. What is the MOST common means of locomotion for a bacteria?1 air bubbles one or more flagella jet-propelled by extruding slime pseudopods 4. Until recently, archae and eubacteria used to be classified together as just “bacteria” because they are very similar.1 True False 5. Some bacteria have an outermost layer called the capsule. What is it made of?1 polysaccharides proteins phospholipids microtubules 6. How are cilia different from flagella?1 Cilia are used for locomotion; flagella are not. 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 beat back and forth; flagella spin around in a circle. 7. All bacteria that are Gram negative are bad/pathogens.1 True False 8. The results from a Gram stain tell us about what part of a bacteria?1 The cytoplasm The cell wall The flagellum The nucleus 9. Which of these is NOT a difference between eubacteria and archae?1 Eubacteria have cell walls made of peptidoglycan, archae do not. Arcahe DNA is wound on spools called histones, while eubacteria DNA is not. Archae have a nucleus and eubacteria do not. Archae has double headed phospholipids in its plasma membrane and eubacteria has a bilayer of single headed phosphopolipids. 10. 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 16: Prokaryotes (part 1) 18: ATP and Glycolysis Back to: 17: Prokaryotes (part 2)
