microspore -> male gametophyte = pollen grain Pollen dispersed by animals or wind Pollination (transfer to stigma) Pollen germinates, pollen tube grows down through style into ovary one cell of pollen -> 2 sperm one sperm fuses with egg other sperm fuses with 2 haploid nuclei -> triploid cell double fertilization zygote --> embryo --> seedling triploid cell --> endosperm ovule -> seed ovary -> fruit: protects developing seeds;
