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

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

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)

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

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)

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

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

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

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?

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

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

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

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

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

Question 12 What plants belong to Phylum Hepatophyta Liverworts
