1. Cyclone smackdown! Origin of Plants
Talk about the last exam for 5 minutes. Thumbs up, middle, or down about how they felt.
RULES: GET INTO TEAMS AND CREATE A NAME. YOU WILL ROCK, PAPER, SCISSORS TO SEE WHO GOES FIRST. THE TEAM THAT ANSWERS QUICKEST AND CORRECTLY GETS THE POINTS
Cyclone smackdown!
Origin of Plants

2. Question 1: 1 POINT Define alternation of generations
Alternating between multicellular haploid and diploid stage

3. Question 2: 1 point Define the characteristics of red algae
They have a red photosynthetic pigment, do not have flagellated life stage, and they are the closest relative to land plants (along with green algae)

4. Question 3: 1 point
Name at least two similarities between land plants and protists
Photosynthetic autotrophs, cellulose cell walls, chloroplasts containing chlorophyll a and b

5. Question 4: 1 point
Name at least 3 reasons for plants to move from water to land
More sun, more CO2, mineral soil, and fewer herbivores (safer)

6. Question 5: 1 point
Green algae are the closest relative to land plants. What is the scientific name for green algae?
Charophyceans
Most likely will have to know this scientific name for sure

7. BONUS! 3 points
Congrats, team! If you get this question right, you will get 3 points!
If you do not get this right, the other team can steal! I will give you 5 minutes to discuss

8. Bonus question for 3 points
List the 5 characteristics that are evidence that Charophyceans are the closest relative to land plants. TRY TO REMEMBER BEFORE LOOKING AT YOUR NOTES!
Rose-shaped complexes that synthesize cellulose (green algae has more of this than any other algae)
Enzymes in peroxisomes
Same structure of flagellated sperm
Formation of phragmoplast (cytoskeletal structure that helps form the cell plate)
Plasmodesmata

9. Question 6: 1 point
List at least 3 differences between Charophyceans and plants
Apical meristems, alternation of generations (charophyceans do not have this), walled spores produced in sporangia, multicellular gametangia, and dependent embryos
What are the female and male parts of the gametangia?

10. Question 7: 1 point
What parts are haploid and what parts are diploid in the alternation of generations?
Gametophyte are haploid and sporophyte are diploid

11. Question 8: 1 point Non-vascular, seedless plants are called what?
Bryophytes

12. Question 9: 1 point What is the dominant stage in bryophytes?
Gametophyte

13. Question 10: 1 point
Meiosis occurs in the _________ stage to produce __________ spores
Meiosis occurs in the sporophyte stage to produce haploid spores

14. Question 11: 1 point
What is the ecological importance of mosses? (ex: peat bogs)
They help to stabilize the CO2 concentrations in the atmosphere

15. Question 12
What plants belong to Phylum Hepatophyta
Liverworts
