1. Virus Mobil Cards
Write the definition of the following terms on 3 mobil cards:
Capsid
Bacteriophage
Vaccine
Explain how viruses reproduce on the card.
Explain 3 examples of viral diseases.

2. BACTERIA!

3. Review Questions Are bacteria prokaryotes or eukaryotes?
Multicellular or Unicellular?
Do they have a cell wall?
How many kingdoms are there for types of bacteria?
What are the two types of bacteria?
What domains are these two types of bacteria part of?
Yes! 2!
Eubacteria and
Archabacteria
Bacteria and Archea

4. ARE BACTERIA LIVING?
YES!

5. Divided into two kingdoms: Eubacteria and Archaebacteria
Heterotroph or autotroph (most use chemosynthesis).
Chemosythesis is when organisms make energy from chemical reactions.

6. The Six Kingdom System: Archaebacteria
Include prokaryotes without membrane bound nuclei
Live in extreme environments without Oxygen
Microscopic
Unicellular
Cell Walls
Autotrophs or Heterotrophs
Oldest fossils are 3.5 Billion years old

7. The Six Kingdom System: Eubacteria
Are prokaryotes that have very strong cell walls
Microscopic
Unicellular
Heterotrophs & Autotrophs
Live in most habitats except extremes where archaebacteria live.
Some cause disease, most are harmless and/or helpful.
Archaebacteria and eubacteria together are called monera and make up the most amount of biodiversity in the world.

8. Bacteria and archaea Similar but different SIMILARITIES: Small
Single celled
Cell wall
Plasma membrane
DIFFERENCES:
Living environments
Shapes

9. Bacterial Shapes Bacilli: rod shaped Cocci: spherical
Spirilla: spiral, corkscrew

10. Structure of a Bacteria
Cell membrane
Cell wall
DNA
Ribosomes

11. Bacteria Growth and Reproduction
Bacteria reproduce in two main ways:
Binary fission – when bacterium doubles in size, it copies its DNA and divides, producing two identical cells.
Conjugation – a hollow bridge forms between 2 bacteria and genes are transferred from one cell to the other (genetic diversity)

12. Bacteria Reproduction: Binary Fission
When a bacteria grows so that it has doubled in size, it replicates its DNA and divides in half
Is this sexual or asexual?
Identical or different daughter cells?

13. Bacteria Reproduction: Conjugation
Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells.

14. Gram staining differentiates types of Eubacteria.
Eubacteria have peptidoglycan and certain lipids in their cells walls that are not present in Archaebacteria.
Gram staining differentiates types of Eubacteria.
Thick cell walls absorb more of the dye and appear dark purple (Gram positive).
Thin cell walls absorb less of the dye and appear pink (Gram negative).

15. We’re not all bad!
Bacteria are most widely known for causing diseases such as strep throat, tetanus, meningitis, and tuberculosis.
However, most bacteria are very useful:
Many are important decomposers in our ecosystem.
Rhizobium provides plants with nitrogen.
A few bacteria are used to clean up small oil spills in the ocean.

16. Antibiotics Antibiotics block the growth and reproduction of bacteria
Used to treat bacterial infections
Bacteria can evolve to become resistant to antibiotics

17. Common Bacteria Strains
Streptococcus
Staphylococcus
Escherichia coli (E. Coli)
Meningococcus

18. Bacteria Facebook Page
You will be given a fact sheet with a type of bacteria and your task will be to create a facebook page for it
You must include:
5 statuses about your specific bacteria from your fact sheet
5 statuses on anything you learned about all bacteria from the notes today
Draw or cut and paste at least 3 pictures of your bacteria
Write at least 4 other types of bacteria that you are “friends” with
