Botany Webquest
First a quick overview of the evolution of plants and then we discus how they work.
Answer the following questions in your lab notebook under Botany Webquest.
1. What kind of an ancestor did all land plants have?
_____________________________
2. Give an example of a non-vascular land plant:

Like all plants, mosses alternate generations.
9. Which generation is dominant?
10. Which generation is parasitic?
11. Ferns and Allies (Pteridophyta and allies) in phylum _______are a huge
