Question 1

Kingdom Plantae

Answer 1

SporicMeiosis•Sterile Jacket•Embryos –sporophyte inside female

Question 2

Bryophyta

Answer 2

Moss, liverworts horworts
–Simple, relatively small–Lack a vascular system•Moist areas•Usually close to the ground–Use water for reproduction•Sperm swim to eggs
upper division lack vascular system

Question 3

Alternation of Generation in Bryophytes

Answer 3

Mature sporophyte (diploid) releases numerous spores (haploid)
•Spores germinate into a protonema(branching structure)–Grows upright with “leaves”, a “stem” and rhizoids
•Gametophyte (haploid) produces gametangia–Archegoniumcontains egg–Antheridium contains antherozoid(sperm)
•Sperm swim to egg and after fertilization sporophyte starts to develop

Question 4

Bryophyta Predominant Phase:

Answer 4

Gametophyte

Question 5

Bryophyta Sporophyte

Answer 5

Obtains nutrients from Gametophyte through foot

Looks like stem with flower

Question 6

Monilophyta

Answer 6

Ferns
Xylem
Phloem
Not water restricted
Needs water to reproduce

Question 7

Xylem

Answer 7

Carry water and minerals from soil (flows up)

Question 8

Ploem

Answer 8

Distribute organic compounds to roots (flows down)

Question 9

Alternation of Generations in Monilophyta

Answer 9

Sporophyte: Diploid
Gametophyte Haploid, spore to gametophyte, Gametophyte is heart shaped
After fertilization, zygote to sporophyte

Question 10

Monilophyta predominant phaseL

Answer 10

Sporophyte

Question 11

Arechegonium

Answer 11

Contains egg

Question 12

Antheridium

Answer 12

Contains sperm (antherozoid)

Question 13

Gametophyte

Answer 13

Haploid, produces gametes

Question 14

Sporophyte

Answer 14

diploid, produces spores

Question 15

Sexual reproduction of plants

Answer 15

Sporic

Question 16

Sporangia

Answer 16

Sac that contains sporophytes
