1. Bacteria

2. Eubacterium Structure
Section 19-1
Peptidoglycan
Cell wall
Cell membrane
Ribosome
Flagellum
DNA
Pili

3. Classification DKPCOFGS Domain Bacteria - Kingdom Eubacteria
Domain Archae - Kingdom Archaebacteria
Domain Eukarya - Kingdom Animal, Plant, Protist, Fungi

5. Classification What is the name of this animal? Puma Cougar
Mountain Lion
Panther

6. Adaptation?

7. Eubacteria Live everywhere cell walls contain - peptidoglycan
Ex. E. coli

8. Archaebacteria Cell walls lack peptidoglycan
genes are similar to eukaryotes
harsh environments
methanogens - mud, animal digestive tracts
halophiles - very salty environments, Great Salt Lake
thermophiles - hot springs

13. Identification Shapes - bacilli, cocci, spirilla
Cell Walls - gram positive, negative
Movement -
flagella
glide
no movement

14. Staphylococcus

15. Spirillum

16. Bacillus

18. Obtaining Energy Autotrophs Heterotrophs Photoheterotrophs -
photoautotrophs - cyanobacteria (everywhere)
chemoautotrophs - hydrothermal vents, energy from chemical reactions
Heterotrophs
Photoheterotrophs -
sun = energy
organic compounds = nutrition

19. Energy Release Obligate Aerobes - require oxygen
Obligate Anaerobes - oxygen deadly
botulinum - causes botulism in unsterile cans, bulging cans
Facultative anaerobes - with or without oxygen
switch between respiration and fermentation, abundant

20. Growth and Reproduction
Some can divide every 20 min.
Binary fission - asexual reproduction
2X normal size, DNA divides and cell division
Conjugation
exchange of genes through a hollow bridge
increases genetic diversity
Endospores - proteins coats form in harsh conditions, up to centuries

21. BINARY FISSION

22. CONJUGATION

24. Bacteria in Nature Producers Decomposers Nitrogen Fixation
Rhizobium – symbiosis with soybeans
Nitrogen  Ammonia
