1. Bacteria
An introduction

2. What do bacteria look like?

3. Answer the following: What kingdom does bacteria belong to?
Are they heterotrophic or autotrophic?
Are they unicellular or multicellular?
Are they eukaryotic or prokaryotic?

4. Where are bacteria found?
With a partner write down as many places you think they might be
Now, narrow it down just to places in school.

5. Bacteria Lab
With your partner, you will be testing 3 places for bacteria.
Write those three down on your lab paper.
Once approved you will be given testing apparatus

6. Testing Apparatus Petri Dish Cotton Swabs (4) Beaker of water
Put your name on the top
Divide the other side into 4 quads
Cotton Swabs (4)
Beaker of water

8. Kingdom Prokaryota Includes two types of bacteria:
Eubacteria & Archaebacteria
Can live just about anywhere, depending upon the species

9. Two new kingdoms?? Eubacteria Archaebacteria Large variety
Live in many different places
Archaebacteria
Ancient bacteria
Live in extremely harsh places that would kill most other organisms

10. Types of Archaebacteria
Thermoacidophiles
Live in hot, acidic places
Halophiles
Live in very salty areas
Methanogens
Anaerobic, produce methane as a byproduct
Decomposers
Often found in rumens

11. Characteristics of Eubacteria
Remember they are prokaryotic
Prokaryotic cell type (no nucleus)
Single Celled
Heterotrophic or Autotrophic
Cell Wall of Peptidoglycan
Cell Membrane
DNA in a ring (plasmid)

12. Extra Structures Aids the survival of the bacteria
Not all bacteria have each one of these
Capsule
Hard outer covering
Flagella
Single hair-like whip
Aids in motion
Endospore
Hard shell around DNA

13. Notorious Bacteria are known to cause sickness, disease, decay, etc.
But they are not all bad all of the time.

14. Good? Decomposers Nitrogen Fixation Food Products Oxygen production
recycle materials
Nitrogen Fixation
Atmospheric nitrogen to ammonia
Food Products
(cheese & yogurt)
Oxygen production

15. Cyanobacteria Photosynthetic Aquatic Ancient
autotrophic
Aquatic
Ancient
Often called “blue-green algae”
This is incorrect!
Algae is a plant, but cyanobacteria is a bacterium

16. Cyanobacteria Lab Fold paper twice to create four quadrants
#1 Spirogyra
#3 Oscillatoria
#2 Nostoc
#4 Anabeana
Fold paper twice to create four quadrants
Label each quadrant:
#1 Spirogyra
#2 Nostoc
#3 Oscillatoria
#4 Anabeana
Work with a partner
Draw and describe what you see!

17. Cyanobacteria Lab
Answer the following questions based on your observations:
Which of the cyanobacteria has a gel-like capsule?
Are these cyanobacteria unicellular or multi-cellular?
What might be 2 reasons these cyanobacteria are good for the earth?
On the next slide tell which is which based on your observations.
