|
Alternation of generations
|
A multicellular diploid (2n) form (the sporophyte) and a multicellular haploid (n) form (the gametophyte).
|
|
Sporophyte
|
Multicellular diploid (2n)
|
|
Gametophyte
|
Multicellular haploid (n);
|
|
Male gametophyte
|
Sperm, or pollen
|
|
Female gametophyte
|
Egg, or embryo sac
|
|
Fertilization
|
The fusion of the male and female gametophytes; a diploid zygote forms, and a sporophyte develops
|
|
Sporophyte
|
The plant, which produces spores through meiosis. the spores divide mitotically, forming haploid gametophytes
|
|
Dominant generation
|
The generation that is easiest to see and that lives longest; generally the sporophyte, especially in angiosperms
|
|
Flowers
|
Highly visual, characteristic reproductive parts of the angiosperm; where meiosis and gamete fusion occur. it typically has four "whorls", or parts: the sepals, carpels, stamens, and petals.
|
|
Stamen
|
The male unit of the plant. it contains the filament and an anther
|
|
Anther
|
Part of the plant that produces the pollen
|
|
Carpel
|
Ovary, style, and stigma; the female parts of the plant
|
|
Stigma
|
Has a sticky surface that serves to trap pollen grains
|
|
Ovary
|
Develops into a fruit upon maturity
|
|
Ovules
|
Inside the ovary; these eventually develop into the seeds of the fruit
|
