stamens produce pollen,pollen transferred via wind or animal to stigma,stigma>ovary,ovules develop,seeds form,fruit develops...this is over-simplified=it is a complex process involving biotic and abiotic factors, plus self-fertilization and cross-fertilization
Where does sexual reproduction occur in?
Overall- Pollination; pollen carried from anther to stigma; sperm nuclei germinates out of pollen grain, goes down style into ovule and fertilizes egg nuclei (double fertilization occurs), Seed develops from ovule and fruit develops from ovary. Next seed is dispersed.
