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

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

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.

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

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

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.

Write down at least 4 exampels

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)
