Terrestrial Plant Diversity (Nonvascular & Vascular)

Question 1

4 Key Factors

Answer 1

Apical Meristems, Alt of Generations, Walled Spores produced in Sporangia, and Multicellular Gametangia

Question 2

Apical Meristems

Answer 2

Point of plant growth, bud at top of a branch

Question 3

Alteration of Generations

Answer 3

two stages of life cycle

Question 4

Walled Spores produced in

Answer 4

Sporangia`

Question 5

Two Distinct Multicellular Stages

Answer 5

Gametophyte (haploid)

Sporophyte (Diploid)

Question 6

Gametophytes are dominant in what kinds of plants?

Answer 6

Non Vascular

Question 7

Sporophytes are dominant in what kinds of plants?

Answer 7

Other Terrestrial Plants

Question 8

Basic Reproduction Progression (4)

Answer 8

1) Sporophyte creates spores (Diploid to haploid)
2) Spores to gametophytes (haploid to haploid)
3) Gametophyte turns to gametes (via mitosis)
4) Egg (n) + Sperm (n) = Zygote (2n)

Question 9

Sporangia

Answer 9

site of spore production

Question 10

Sporocyte

Answer 10

undergo meiosis to form haploid spores

Question 11

What are spores coated in?

Answer 11

Sporopollenin

Question 12

Gametangia

Answer 12

Site of gamete production

Question 13

2 types of gametangia

Answer 13

Archegonia and Antheridia

Question 14

Archegonia

Answer 14

Egg

Site of fertilization

Question 15

Antheridia

Answer 15

Sperm

produce and release

Question 16

Homosporus

Answer 16

one type of spore

ex. gametophyte

Question 17

Heterosporus

Answer 17

two types of spores

ex. angiosperms and gymnosperms

Question 18

Green Algae (4)

Answer 18

1) Adult phase is haploid-no multcellular sporophytes
2) No alteration
3) No zygote
4) 99% of life = Haploid
