Across
  1. 5. gram-positive bacteria that have species that cause strep throat
  2. 7. form of HGT in which bacteria take DNA from organisms in their environment
  3. 9. archaea that have gas-filled vesicles that allow to float in well-lit surface waters; photoheterotrophs
  4. 12. proteobacteria that lives in human gut and is very well studied - scientists have isolated proteins/hormones from it
  5. 14. organotrophic proteobacteria that has a symbiotic relationship with plants - takes sugars from plants and produces ammonia for plants
  6. 17. bacteria that when prepped for microscopy have a cell wall that stains purple
  7. 18. rod-shaped gram-positive bacteria that ferment sugars to form lactate - can lead to spoiled milk but is used to make yogurt
  8. 19. organism that cannot live in environments with oxygen or does not need oxygen to survive
  9. 22. hair-like fragments that can extend from the surface of a bacterium and "pull" other organisms toward it; can also allow bacterium to attach to surfaces
  10. 23. well-known, widespread prokaryotic organism that may or may not cause disease
  11. 25. not as well-known prokaryotic organism that lives in extreme environments
  12. 26. the most diverse bacterial group
  13. 27. spiral-shaped bacterium
  14. 28. sphere-shaped bacterium
  15. 29. gram-positive decomposers that give soil "earthy smell" - antibiotics vancomycin & streptomycin were isolated from these
  16. 32. proteobacteria that lives in human stomach but can produce ulcers which can lead to cancer
  17. 33. very important photoautotrophic bacteria - first to produce oxygen gas as a byproduct of metabolism - led to oxygen-rich atmosphere
  18. 34. primary mode of bacterial replication in which parent cells produce 2 genetically identical daughter cells
  19. 35. form of HGT in which bacteria transfer plasmid DNA to other bacteria
Down
  1. 1. prokaryotic organism that produces energy by breaking down material of dead organisms
  2. 2. bacteria that can cause chlamydia
  3. 3. archaea that break down methane for energy
  4. 4. lithotrophic proteobacteria that is large enough to see with the naked eye
  5. 5. spiral-shaped bacteria that live in the guts of cattle and help these digest cellulose
  6. 6. prokaryotic organism that produces energy using sunlight, CO2, and water
  7. 8. archaea that live in extremely hot environments
  8. 9. form of bacterial replication in which bacteria acquire DNA from outside source
  9. 10. the process of taking nitrogen gas from the atmosphere & converting it to ammonia
  10. 11. causes respiratory disease tuberculosis - very deadly and kills almost 1 million people/year
  11. 12. archaea that live in extremely salty environments
  12. 13. bacterium isolated from a volcanic spring in Yellowstone National Park - DNA polymerase enzyme was isolated from this bacteria & allows us to conduct PCR
  13. 15. prokaryotic organism that produces energy by breaking down inorganic compounds, such as methane, through redox reactions
  14. 16. proteobacterium used for GMOs - has plasmid that can produce tumors in plant roots
  15. 20. organism that can survive and thrive in oxygen-rich environments/needs oxygen to live
  16. 21. prokaryotic organism that produces energy by breaking down organic compounds - carbohydrates, lipids, proteins
  17. 24. rod-shaped bacterium
  18. 30. organisms that can produce energy using sunlight or by breaking down organic molecules
  19. 31. form of HGT in which DNA is transferred between bacteria through bacteriophage
