2. Kingdoms Archaebacteria & Eubacteria
Essential Question: What are the general characteristics of bacteria?
Kingdoms Archaebacteria & Eubacteria
Bacteria

3. What do you already know?
What are the characteristics of life?
What are prokaryotes?

5. What are bacteria?
Microscopic, Unicellular, Prokaryotic organisms containing DNA and ribosomes.
May be autotrophic or heterotrophic
Bacteria are LIVING!!!! They have ALL the characteristics of living organisms.
Found everywhere on earth!

6. Basic Structure of Bacteria
Ribosome
Cell Membrane
Cell Wall
carbohydrates that makes up cell wall
DNA
Flagella
Pilli
Movement
Attachment & transfer of DNA

7. Basic Structure of Bacteria
Bacterial cell wall is made up of the carbohydrate peptidoglycan
Pilli are used for attachment and for exchange of DNA during sexual reproduction
Flagella are used for movement
Not all bacteria have flagella.

8. Bacteria Shapes Bacteria are categorized by three distinct shapes:
video: bacteria shapes
Bacteria are categorized by three distinct shapes:
rod-shaped
(bacilli)/bacillus
Ex: Bacillus cereus
spiral
(spirilla)/spirillum
Ex: Spirillum volutans
spherical
(cocci)/coccus
Ex: Micrococcus luteus

9. Name These Bacteria Shapes

10. Bacteria Kingdoms
Archaebacteria
Eubacteria
video: bacteria habitats

11. Archaebacteria High Temperatures: Thermophile
Live in extreme, harsh environments and are called extremophiles
High Temperatures: Thermophile
High/Low pH: Thermoacidophile
High Salt Concentration: Halophile
Grand Prismatic in Yellowstone’s largest hot springs basin
Great Salt Lake once thought to be lifeless is teeming with salt-tolerant bacteria
Lemonade Spring in Yellowstone highly acidic

12. Eubacteria: “true/common bacteria”
Very diverse group of bacteria that live everywhere!

13. Aerobic Respiration: WITH OXYGEN Anaerobic Respiration: withOUT Oxygen
May be heterotrophic (do not make own food)
Aerobic Respiration: WITH OXYGEN
Anaerobic Respiration: withOUT Oxygen
May be autotrophic:
Photosynthetic
ex: cyanobacteria found in
lakes & ponds use blue chorophyll for photosynthesis

15. Questions??

16. CONCEPT REVIEW: True or False
Members of Archaea live in extreme environments.
TRUE

17. CONCEPT REVIEW: True or False
Members of Kingdom Eubacteria are lovers of extremes.
FALSE

18. Warm-Up MON 12/11; PART 1
Use the following dichotomous key to identify butterfly fish C.
Make sure you follow the rules for writing scientific names!!!

19. CONCEPT REVIEW: True or False
The cell walls bacteria contain peptidoglycan
TRUE

20. Which micrograph shows bacillus bacteria?
CONCEPT REVIEW:
Which micrograph shows bacillus bacteria? A B C

22. Warm-Up Mon 12/11; PART 2
A) What is the difference between Kingdoms Archaebacteria & Kingdom Eubacteria?
B) What are at least 3 similarities (think general characteristics of bacteria)?

23. Bacteria Function & Reproduction
Essential Question: How do bacteria reproduce? How do bacteria cause disease and what factors control the growth of bacteria?

24. Not All Bacteria Are Bad!!!

25. Bacteria Function
Bacteria have a variety of important uses:
Decompose organic matter (recycle nutrients from dead organisms)
Human health (bacteria on skin help prevent infection & bacteria in gut helps digest food & make vitamins)

26. Bacteria Function
Help make food (buttermilk, yogurt, cheese, pickles, and olives)
Nitrogen fixation (chemically changes nitrogen gas, N2, into ammonia, NH3, so plants can make amino acids)
BioTechnology (used to make antibiotics, insulin)

27. Bacteria Reproduction
Binary Fission: asexual; cell splits into 2 identical cells.

28. Bacteria Reproduction
Conjugation: cells exchange genetic info through pilus.

29. Bacteria Form Endospores
If conditions are unfavorable, forming an endospore allows bacteria to remain dormant until conditions are favorable again.

30. Some Bacteria Are Bad!!!
Some bacteria cause diseases like Strep throat, pneumonia & food poisoning
Controlling the growth of bacteria
Antibiotics: Medicine taken to kill bacteria AFTER infection
Vaccines: Shot taken to PREVENT bacterial infection
Disinfectants: Used to kill bacteria on surfaces like countertops, toilets

31. Bacteria Lab

32. Warm-Up Fri 2/10
Use the following dichotomous key to identify butterfly fish C.
Make sure you follow the rules for writing scientific names!!!
