Station Activity: Bacteria & Virus Review
Station #1 – Virus Life Cycle
1. Virus (bacteriophage) attaches to host cell (bacteria)
2. Virus injects genetic material inside host.
3. Viral DNA takes over and creates more viral parts.
4. The viral parts assemble to create more viruses.
5. The new viruses burst out from the host cell in order to spread.
Station #2 – Virus Size
1. bacteria cell
2. 7500nm – 130 nm = 7370nm
3. 7500nm – 750nm = 6750nm
4. genetic material & protein coat
Station #3 – Viruses & Vaccines
1. cowpox
2. antibodies
3. white blood cells
4. polio

2. Good
3. Good
4. Good
5. Bad
Station #9 – Good or Bad Bacteria?
1. Autotrophic – able to make its own food
2. Heterotrophic – must feed off of something else
3. Aerobic – requires oxygen
4. Anaerobic – does not need oxygen
5. a. Heterotrophic
b. Heterotrophic
c. Autotrophic
d. Autotrophic
e. Heterotrophic
Station #10 – Bacteria and Natural Selection
1. There is VARIATION in the bacteria population. Some bacteria are resistant to the
antibiotic. These bacteria are better ADAPTED to live in the presence of antibiotics.
They SURVIVE, REPRODUCE, and pass on the gene for this trait. Over time, more of the
bacteria are resistant to the medicine and the population has EVOLVED.
2. Helmet = Mutation or trait (variation) allowing bacteria to RESIST the antibiotic
3. Binary Fission
