1. Bacteria

2. -Prokaryotes – no cell nucleus, no membrane organelles -unicellular -have a cell wall

3. Bacteria Shape and Growth -3 shapes -rod – bacilli- -sphere – cocci- -spiral – spirilla- -Growth arrangements -paired colonies- diplo- -chains- strepto- -clumps- staphylo-

6. Bacteria Reproduction bac vid -Binary Fission (asexual)- the DNA replicates and the cell divides in half.

7. Bacteria Reproduction con’d -Conjugation (sexual) - protein bridge is formed between 2 bacteria, DNA is exchanged

8. Endospores -endospores- a tough covering containing bacteria DNA. -bacteria will lie dormant until conditions are favorable

9. Archaebacteria (Kingdom 1) -Bacteria that live in extreme environments called extremophiles

10. Heat Loving Bacteria, Thermophiles -live in hot springs and thermal vents in the ocean (100ºC)

11. Methane Producing Bacteria, Methanogens -Live in marshes and cow stomachs -Used in sewage treatment plants

12. Salt Loving Bacteria, Halophiles - Live in the dead sea and salt lakes

13. Eubacteria (Kingdom 2) -commonly found everywhere -grouped by how they get energy

14. Heterotrophic -most common -often parasites

15. Photosynthetic autotrophs -do photosynthesis to produce energy -contain chlorophyll -found in water

16. Chemosynthetic autotrophs -use inorganic compounds to make energy (nitrogen, sulfur) -nitrogen fixing bacteria

17. Bacteria Pros tasty vid -fix nitrogen -help digest food in our intestines -decomposers -used to make food (cheese, yogurt)

18. Bacteria Cons -Cause Diseases -Over use of antibiotics has created more resistant bacteria.
