1. Goals Today: Take notes on Viruses
Venn Diagram (instructions on slide 8)
Study Island (DUE TOMORROW!)

2. A virus is the smallest microbe that destroys healthy cells
Viruses
A virus is the smallest microbe that destroys healthy cells
Viruses have NO cells

3. Viruses
Viruses do not act like living things – they can’t eat, grow, break down food, or use oxygen.
A virus CANNOT function on its own.

4. Are they alive?
A virus can only reproduce inside a living cell that serves as a host
A host is a living thing that a parasite lives on or in

5. Are they alive?
While inside the cell, the virus forces the cells to make viruses rather than making healthy new cells

6. Viruses contain DNA that they inject into the healthy cell
Viruses contain DNA that they inject into the healthy cell. The healthy cell will make copies of this new DNA, making more virus cells.

7. Write down at least 4 exampels

8. Venn Diagram – due before you leave class
Create a Venn Diagram comparing and contrasting Bacteria and Viruses
You need 4 facts in each section from your notes
You need 2 additional facts for each section from Differn (see symbaloo)
