Alternation of Generations

sporophyte generation

diploid stage (2n), produce spores by meiosis

Heterspory

having different gender spores, - Megasporangium - microsporangium seed plants

Gametes

mature haploid (n) cell that is able to unite with another in reproduction to form a zygote

Spores

Produced by meiosis. Grow into haploid organisms by mitosis.

homospory

the production of just one type of spore in seedless, vascular plants

sporocyte

A diploid cell (2n) that undergoes meiosis and generates haploid spores

gametangia

A reproductive organ that houses and protects the gametes of a plant

sporophyte

Diploid (2n) phase of an organism

gametophyte

Haploid (n), or gamete-producing, phase of an organism

What does the gametophyte contain?

gametangia gametes

gametophyte generation

haploid stage (n),

What does the sporophyte contain?

sporangium sporocyte

sporangium

spore capsule in which haploid spores are produced by meiosis

alternation of generations

the alternation between the diploid (2n) sporophyte and the haploid (n) gametophyte in a plant's life cycle
