kindom plantae

Question 1

plant life cycle (alternation of generations)

Answer 1

gametophyte (n) -> mitosis (egg or sperm) -> fertilization -> zygote (2n) -> embryo (2n) -> sporophyte (2n) -> sporangia -> (spore mother cell) 2n-meiosis -> spores (n n n n) ->gametophyte (n)

Question 2

sperm-producing structures of non-vascular and seedless vascular plants are called

Answer 2

antheridia

Question 3

antheridia develop on the _______ generation

Answer 3

gametophyte

Question 4

what sex is an archegoniophore

Answer 4

female

Question 5

what sex is an antheridium

Answer 5

male

Question 6

fern gametophytes are (each individual produces)

Answer 6

bisexual / transsexual (produce both male and female/ archegonia and antheridia)

Question 7

what is the function of strobili

Answer 7

contain sporangia

Question 8

what phylum is liverworts

Answer 8

hepaticophyta

Question 9

what phylum is mosses

Answer 9

bryophyta

Question 10

what phylum is hornworts

Answer 10

anthocerophyta

Question 11

what phylum is ferns

Answer 11

pterophyta

Question 12

what are the functions of rhizoids?

Answer 12

anchor the plant and absorb water

Question 13

how do the positions of the archegonium and antheridium relate to their reproductive function?

Answer 13

sperm from the antheridia are released and washed into the venter of the archegonia which contains the egg

Question 14

[liverworts] what is the function of the foot? haploid or diploid? what is the functional significance of the response of elaters to moisture?

Answer 14

absorb nutrients, haploid, coil or expand based on temperature to collect water and release spores

Question 15

how does the symmetry of a moss gametophyte compare with that of a liverwort gametophyte?

Answer 15

moss- symmetrical around a central point, liverwort- division into two mirror-image halves

Question 16

where is the egg located in the archegonium?

Answer 16

in the venter

Question 17

are sperm haploid or diploid?

Answer 17

haploid

Question 18

is the sporophyte more prominent in mosses or liverworts?

Answer 18

moss

Question 19

what is the adaptive significance of the seta of the sporophyte growing well above the mat of the gametophytes?

Answer 19

better dispersal of spores, wind can tae spores away if seta is taller

Question 20

what process produces spores? is the capsule haploid or diploid?

Answer 20

meiosis, diploid

Question 21

like bryophytes, ferns require water for fertilization. why?

Answer 21

sperm moves in the water to the egg

Question 22

life cycle haploid vs diploid

Answer 22

meiosis to fertilization = haploid, other half diploid
