II. Basic Vocab:
 Autotroph: Makes its own food

Heterotroph: Has to consume food

Eukaryote: Has a nucleus

Prokaryote: Doesn’t have a nucleus (Bacteria ONLY)

Multicellular: Many celled (can see them)

Unicellular: One celled (need a microscope to see)

Pathogenic: Causes disease
Some are edible
Make antibiotics
Must reproduce in
a host cell
Treated with
antivirals
Prevented with
vaccines
What is the difference between the two cells above?
The one on the left is a eukaryotic protist cell. The one on the right is a prokaryotic bacteria cell
III. Bacteria
1. Label the three shapes of bacteria.
Cocci
Bacilli
Spirilla
2. In what ways can bacteria be harmful? Bacteria can cause disease (pathogen)
3. In what ways can bacteria be helpful? Bacteria help us digest food, help in food production and act
as decomposers cycling nutrients.
4. Label the bacterial cell. Include: DNA, cell wall, ribosomes, cilia, and cytoplasm
5. What type of bacteria live in harsh environments? Archaebacteria
6. What type of bacteria live everywhere? (Except harsh environments) Eubacteria
IV. Viruses
1. What do viruses need to reproduce? Viruses have to use a host cell to reproduce
2. What are the similarities and differences between a virus and a cell?
Similarities: DNA/ Pathogenic
Cell: Living / Larger / Prokaryotic or Eukaryotic / Surrounded by cell membrane
Virus: Nonliving / Small / Surrounded by capsid
3. Put the steps of the lytic cycle in order. (Replicate, Attach, Enter, Release)
Attach / Enter / Replicate / Release
4. Why is the lysogenic cycle longer than the lytic cycle? The virus stays dormant/hidden in the host
cell for long periods of time making copies of itself. It takes longer for a person infected to feel
symptoms.
5. What are some of the ways that viruses can spread? Coughing, sneezing, bodily fluid, direct contact
6. What type of cell does HIV infect? How do people with HIV actually die? HIV destroys the immune
system cells. People with HIV eventually die from diseases a healthy person would be able to fight off
7. Label the virus
8. What is the purpose of a glycoprotein receptor on the outside of a virus? The projections allow for
attachment to the host cell.
V. Protists
1. What are cilia, flagella and pseudopods used for? Movement
2. Euglena are plant like protists that are attracted to light. Why are Euglena attracted to light?
Euglena are attracted to light because they are autotrophic and need light to carry out
photosynthesis.
3. Where do most Protists live?
They are aquatic organisms that live in the water.
VI. Fungi
1. Label the fungus. Include the: fruiting body, hyphae, and mycelium
2. What role do fungi play in our environment? Decomposers
3. What helpful medicine do fungi help make that kills bacterial pathogens?
antibiotics
4. Are Fungi motile or non-motile?
Non-motile (cannot move)
