gametophyte
haploid phase of life cycle...produces gametes
sporophyte
diploid phase of the life cycle
Alternation of generations
The two distinct reproductive phases of green plants in which stages alternate between haploid cells and diploid cells (gametophyte cells and sporophyte cells).
Protenema
Small green threadlike structure...develops from the spore
rhizoid
The "root-like" part of moss that goes down into the earth
Archegonia
female sex organ of moss
Antheridia
male sex organ of moss
Calyptra
A capsule covered by a cap-like remnant of the old archegonia
embryo
2n (diploid tissue)...sporophyte plant
Meiosis
(a.k.a. reduction division)...chromosome number (2n) in each cell is reduced in half (n)
Sori
form spores on underside of ferns
Prothallium
heart shaped gametophyte plant
seed
fertilized ripened ovule of a gymnosperm
gymnosperm
"naked seed"
homospory
one type of same sized spores are produced
heterospory
two different spores of unequal size
microspore
(a.k.a. pollen grain)...produced by the male
megaspore
produced by female (larger than the microspore)
pollination
the transfer of pollen from the male to the female part of a flower
staminate cone
male reproductive structure
ovulate cone
female reproductive structure
ovule
produced by megasporangia...developes into seed
endosperm
stored food for embryo...(refer to p. f11)
pollen grain
modified microspore of seed plants
fruit
ripened ovary containing seeds
cotyledons
embryonic leaves
sepals
small leaf-like structures, which help protect the closed flower bud
petals
colorful structure leading pollinators toward the reproductive parts of the flower
stamen
male reproductive structure (anther, filament)
pistil
female reproductive structure (stigma, style, ovary)
double fertilization
1 sperm-->1 egg = zygote(2n)
other sperm--> 2 polar nuclei = endosperm(3n)
