Chapter 27 Questions 1) What are the three basic shapes of bacteria? 3) How are bacterial cell walls different for plant cell walls? 4) What is Peptidoglycan? 5) What is the structural difference between Gram (–) and Gram (+) bacteria? And how does the structure relate to the staining procedure/results? 6) a) How do many antibiotics hurt bacteria? And why don’t they harm animals? (Alexander Fleming discovered Penicillin, which acts in this way. Other antibiotics like Streptomycin actually inhibit bacterial protein synthesis. These also don’t harm us, because the ribosomes in bacteria are different from Eukaryotes.) b) What is an antibiotic, and how do we get them? 7) What are the two functions of pili? 8) What are the two reasons why Gram (-) bacteria tend to be more of a threat to human health? 9) How do bacteria without flagella move?
