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
