1. Bacteria

2. Prokaryotes vs. Eukaryotes - “pro” = before - “karyon” = nucleus NO nucleus NO organelles Small, less complex Circular DNA, floats in cytoplasm i.e. Bacteria - “eu” = true - karyon” = nucleus Have nucleus Organelles Large, complex Linear DNA, in nucleus i.e. Plants & Animals

3. 2 Kingdoms of Prokaryotes

4. Cyanobacteria First Photosynthetic Prokaryote Oxygen is produced in oceans and creates ozone

5. 3 Shapes 1. Coccus (round) 2. Bacillus (rod) 3. Spirillum (sprial) Escherichia coli Staphylococcus aureus Streptococcus pyogenes

6. Gram-staining Method used to classify bacteria into 2 groups: Gram-positive vs. Gram-negative stains peptidoglycan in cell walls of the bacteria

8. Endospores Specialized “resting” cells dormant cell formed by certain bacteria that can survive very harsh conditions (heat, cold, poison)

9. Example – Closdridium botulinum Caused from improper canning Produces neurotoxins that lead to paralysis

11. Movement Flagella – long whip- like tails pili – short projections which allow them to stick to their hosts, their environment or each other.

12. Asexual ReproductionAsexual Reproduction – Binary Fission

13. Methods of Obtaining Energy Photosynthesizers Chemoautotrophs Heterotrophs
