1 - $100 n Plants are most closely related to a group of _____ called ______ n Plants are most closely related to a group of GREEN ALGAE called ZYGNEMATOPHYCAE

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

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

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

1 - $500 n Describe what Alternation of Generations means. Do all plants do this? What does the sporophyte produce? What does the gametophyte produce? n https: //www. youtube. com/watch? v=1 bjgb. KT 5 u. A w

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

2 - $200 n What is the red arrow pointing to? What is the function of this structure? n 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)

2 - $300 n 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)

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

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

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

3 - $200 n What adaptations do seedless vascular plants have that bryophytes don’t have? Thick waxy cuticle that minimizes water loss (i. e. prevents desiccation) n 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) n

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

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

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

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

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

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

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

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

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

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

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