Final Vocab (mostly reproduction)

Question 1

Sporophyte

Answer 1

diploid phase of alternation of generations, contains the sporangia which produces spores (most of plant in heterosporous plants, dependent on gametophyte in homosporous plants)

Question 2

Gametophyte

Answer 2

haploid phase of alternation of generations, has gametangia on it which produce gametes and eventually the zygote

Question 3

Gametangia

Answer 3

structures on gametophyte which produce haploid gametes

Question 4

Sporangia

Answer 4

structure in which spores are formed (meiosis)

Question 5

Megasporocyte

Answer 5

female cell which undergoes meiosis to produce 4 haploid megaspores (embryo in heterosporous plants)

Question 6

Microsporocyte

Answer 6

male cell which undergoes meiosis to produce pollen grain (young microgametophyte) and eventually pollen tube (mature microgametophyte)

Question 7

Megagametophyte

Answer 7

female gametophyte (egg in heterosporous plants)

Question 8

Microgametophyte

Answer 8

male gametophyte (young = pollen grain, mature = pollen tube in heterosporous plants)

Question 9

Spore

Answer 9

reproductive cell in non-seeded plants/homosporous plants, becomes the zygote after fertilization

Question 10

Microspore

Answer 10

male spore

Question 11

Megaspore

Answer 11

female spore

Question 12

Megasporangia

Answer 12

structure in which female spores are formed

Question 13

Microsporangia

Answer 13

structure in which male spores are formed

Question 14

Microphyll

Answer 14

leaves with one vein/vascular bundle (often very small, but not technically required to be)

Question 15

Megaphyll

Answer 15

normal leaves

Question 16

Rhizoid(s)

Answer 16

hairs that help anchor plant (in plants that cannot produce true roots)

Question 17

Homosporous

Answer 17

plant that produces one type of spore - gametophyte dominant (bryophytes)

Question 18

Heterosporous

Answer 18

sporophyte dominant and have multiple sporangia in elaborate sporophyte

Question 19

Sorus

Answer 19

cluster of sporangia on underside of fern leaves. singular.

Question 20

Indusium

Answer 20

holds sori to bottom of fern leaves

Question 21

Rhizome(s)

Answer 21

underground stem, in fern “trees”

Question 22

Gynecium

Answer 22

entire female reproductive structure

Question 23

Angecium

Answer 23

entire male reproductive structure

Question 24

Antheridium

Answer 24

male gametophyte in briophytes

Question 25

Archagonium

Answer 25

female gametophyte in briophytes
