10. What makes up the cell walls of fungal cells? What organic compound is this made from?

11. Using information from the Fungi PowerPoint, webquest, and/or your book develop a dichotomous key that separates kingdoms and eventually leads to the 4 fungi phyla, mycorrhizae, and lichens.

 

Step 1. Separate kingdoms
