1. Previously all classified KINGDOM MONERA
Bacteria
Previously all classified KINGDOM MONERA

2. Bacteria Characteristics
Prokaryotic
Unicellular
Some autotrophic (cyanobacteria)
Some heterotrophic
Some chemotrophic
Contain Cell Walls

3. Two Kingdoms of Bacteria
Archeabacteria
Most primitive organisms on earth
Found in very harsh environments
Eubacteria
“True Bacteria”
Disease causing bacteria in this group

4. Evolutionary Importance of Bacteria
The oldest fossil evidence on earth is that of Archaebacteria.
Archaebacteria are believed to be the ancestors of both Eubacteria and the other eukaryotic kingdoms

5. The Classification of Bacteria
Classification is based on shape and arrangement of individual cells

6. Coccus (Cocci)
Spherical Shaped bacteria

7. Bacillus (Bacilli)
Rod Shaped Bacteria

8. Spirillum (Spirilla)
Spiral Shaped Bacteria

9. Bacterial Arrangements
“Diplo-”--pair of cells
“Strepto”--Chain of cells
“Staphylo”—Cluster of cells

10. Draw the following bacterial shapes and arrangements
Diplospirillum
Streptobacillus
Staphylococcus

11. Positive contributions of bacteria
Decomposers
“Fix” nitrogen into a useable form
Food production—yogurt, cheese, etc.
Sewage Treatment
Clean Oil Spills
Source of antibiotics

12. Negative affects of Monerans
Disease
Syphilis, gonorrhea, tuberculosis, strep throat, botulism, etc.
Food Spoilage
