1. The megasporangium in the ovules undergo meiosis and turn into haploid megaspores where the surviving megaspore develops into a female gametophyte
2. The microsporangia in other pollen sacs undergo meiosis and become haploid microspores, these microspores then develop into pollen grains (male gametophytes) these pollen grains contain tube cells and generative cells
3. The pollen is carried ti the stigma of a flower by the wind or by insect or animal (pollination)
4. The tube cells form pollen tubes down stigma and style ovary
5. Pollen tub enters the ovule through micropyle. The generative cell produces sperm, which travels through the pollen tube into the ovule. The sperm unites with the egg and the zygote becomes an embryo
6. Ovules develop into seeds, ovary develops into fruit which bursts to release seeds to start the cycle over again
