  2. 6. grape-like clusters of cells
  3. 7. used in conjugation (connection and exchange of genetic material) between bacterial cells
  4. 8. sites of protein synthesis
  5. 12. flagella are dispersed randomly over surface of cell
  6. 16. movement of bacteria in response to chemical signals
  7. 17. small, bristle-like fibers sprouting off the surface of many bacterial cells, allows tight adhesion to assist bacteria in colonization and infection
  8. 18. polysaccharide “glue”, can be loose slime layer or denser capsule
Down
  1. 1. polysaccharide and protein component of bacteria cell walls, gram positive have thick layer and gram negative have thin layer
  2. 2. polysaccharide only component of gram negative bacteria cell walls
  3. 4. community of bacteria, “strength in numbers”, responsible for persistent colonization of teeth, plastic catheters and implanted medical devices
  4. 5. bilayer that makes up cell membrane
  5. 9. rod-like bacterial shape
  6. 10. twisted bacterial shape
  7. 11. archaea cell wall component, carbohydrate and protein composition
  8. 13. round bacterial shape
  9. 14. example of acid-fast bacteria
  10. 15. nonessential small pieces of DNA in bacteria, encode for drug resistance and toxin/enzyme production
