Final Jeopardy

2. 1 - $100
Plants are most closely related to a group of _________ called ___________
Plants are most closely related to a group of GREEN ALGAE called ZYGNEMATOPHYCAE

3. 1 - $200
Name the three extant groups of plants and put them in order of oldest to youngest
1) nonvascular
2) seedless vascular
3) seed plants

4. 1 - $300
What were the first type of plants on land? What phyla does this group belong to?
Liverworts
Belong to Bryophytes (nonvascular plants)

5. 1 - $400
Name all of the seedless vascular plant groups common name AND scientific name
Lycophytes - Lycophyta
Ferns – Pteriodphyta
Horsetails – Equisetophyta
Whisk ferns - Psilophyta

6. 1 - $500
Describe what Alternation of Generations means. Do all plants do this? What does the sporophyte produce? What does the gametophyte produce?

7. 2 - $100 What is the dominant phase of the life cycle in Bryophytes?
Gametophyte (n)

8. 2 - $200
What is the red arrow pointing to? What is the function of this structure?
The red arrow is pointing to a gemmae cup. This structure is used to reproduce asexually in Phylum Hepaticophyta (liverworts). The gemma detaches from parent and develops into a new individual (fragmentaion)

9. 2 - $300
Describe the male and female gametophyte (where are the sperm and egg produced?)
Sperm are produced in antheridium (which is male gametophyte)
Egg is produced in archegonium (female gametophyte)

10. 2 - $400 What do mosses need to reproduce? Why? They need water!
Because the sperm are flagellated and need to swim to the egg
“Mosses do it in the rain” –Colbert

11. 2 - $500 What is this a photo of? What is the function of this?
Peristome teeth (located on sporophyte of mosses)
Function is to disperse spores

12. 3 - $100
During the Carboniferous period (~300MYA), what was the dominant plant vegetation on earth?
Seedless vascular plants!!!!
Shit ton of ferns

13. 3 - $200
What adaptations do seedless vascular plants have that bryophytes don’t have?
Thick waxy cuticle that minimizes water loss (i.e. prevents desiccation)
Aerial parts of plants not in contact w/ water and mineral nutrients; have vascular transport tissues consisting of xylem (water and minerals) and phloem (sugars)

14. 3 - $300
What is the dominant phase of the life cycle in seedless vascular plants?
Sporophyte (2N)

15. 3 - $400 Define homosporous vs heterosporous
Homosporous – one size of spore
Can be bisexual or hermaphroditic gametophytes
Heterosporous – two sizes of spores (different sexes; male and female)

16. 3 - $500 What are two water conducting cells found in xylem?
Tracheids and vessel elements – both increase structural support

17. 4 - $100
What does the word “gymnosperm” mean?
Naked seed

18. 4 - $200 What is the dominant phase of the life cycle in gymnosperms?
Sporophyte (2N)

19. 4 - $300
What phylum does this gymnosperm belong to?
Phylum Pinophyta

20. 4 - $400 What phylum does this Gymnosperm belong to?
Phylum Ginkgophyta

21. 4 - $500 Conifers is the common name used for what?
Both phylum pinophyta (pines, firs, spruces and larches) and phylum cupressophyta (yews, redwoods and sequoias)

22. 5 - $100 Which phase is dominant in the life cycle of in Angiosperms?
Sporophyte (2N)

23. 5 - $200 What is the difference between Gymnosperms and Angiosperms?
Gymnosperms have seeds which are naked
Angiosperms have seeds which have a protecting covering AND fruits

24. 5 - $300 What is the difference between pollination and fertilization?
Pollination is deposition of pollen on the stigma
Fertilization is fusion of egg and sperm

25. 5 - $400
The female portion of the flower is referred to as what? Male portion is referred to as?
Female = pistil
Male = stamen

26. 5 - $500 Ovules mature into _______ Ovaries mature into _______ Seeds
Fruits

27. Final Jeopardy What are viruses composed of? Proteins Nucleic acids
Sometimes lipids
