Conifer and Angiosperm Reproduction April 19th 2016

Alternation of Generation Sporophyte (2N)  Spore (N)  Gametophyte (N)  Gametes (N)  Zygote (2N)

What about for Conifers? Sporophyte (2N)  Spore (N)  Gametophyte (N)  Gametes (N)  Zygote (2N)

What about for Conifers? Sporophyte (2N)  Spore (N)  MEGASPORANGIUM (where BIG spores are produced) MICROSPORANGIUM (where little spores are produced)

What about for Conifers? Sporophyte (2N)  Spore (N)  MEGASPORE MICROSPORE

What about for Conifers? Spore (N)  Gametophyte (N)  Ovule (N) Pollen grain (N) MEGASPORE MICROSPORE

What about for Conifers? Gametophyte (N)  Gametes (N)  Egg Sperm Ovule Pollen grain

What about for Conifers? Gametes (N)  Zygote (2N)  Egg Sperm Zygote Seed
