1. Name five basic adaptations that enabled the transition from green algae to land plants?
2. What ecosystem services do plants provide? Describe four.
3. How does plant photosynthesis affect atmospheric carbon dioxide (CO2) levels? How
does it affect atmospheric oxygen levels? What is the relationship between plants,
photosynthesis and fossil fuels such as coal?
4. What are the three major plant groups? Give examples of each. Are all seed plants similar?
According to the fossil record, which groups appear first, second and third. Are plants adapted
for drier conditions found early or they late arrivals in the fossil record?
5. What function does the plant cuticle serve? What are guard cells and why are they necessary to
land plant life?
6. Use the terms archegonia, antheridia, and gametangia in a single sentence that defines all three
terms.

7. How do plants protect themselves from ultraviolet (uv) radiation? Why is uv radiation more of a
problem on land that it is for aquatic algae?
8. Draw and Discuss Alteration of Generations.
9. Looking at the life cycles above, are spores or gametes more genetically diverse? Why do you
say this is the case?
10. How do mosses and ferns avoid self-fertilization? Which generation is dominant in mosses –
sporophyte or gametophyte? Which is dominant in ferns – gametophyte or sporophyte
11. Why is a sporophyte-dominant life cycle (as seen in ferns and seed plants) advantageous
Study Tips for Biol 211:
1. Attend Class
2. Learn the Vocab (Put things into your own words)
3. Grab a friend and tell them about a concept/experiment you learned about in class. Teaching
is one of the best methods for learning/retaining information.
4. Skim material for General Concepts BEFORE and AFTER Class!!!!!
5. Understanding is more important than memorizing.
6. Space out your studying (Study smaller amounts, more frequently. No all-nighters)
7. Visit Dr. Boury’s office hours: MTWF: 10:00-11:30am in 201 Science I
8. Create study groups (you can never have too many friends)
9. Complete the study guides.
10. Have fun.
