Protists

Laboratory Exercise and Notes

The goal of this exercise is to learn about the protists. We will study major phyla and for most of the phyla, we will study representative genera.

For each specimen:

1)      Read the information in The Biology Web for that specimen. Click here to go to the lecture notes on protists.

2)      Create notes. Your notes can be used on the quiz. They should include a drawing and discription and significant information such as life cycle, commercial value, ecological significance, and unusual characteristics.
