The Generative cells makes a tube when it gets on the stigma to penetrate the ovary.The central cells meet up with the discharged sperm nuclei to make the egg nucleus which has an embryo that is haploid, a new sporophyte empryo that is diploid and finally a triploid endosperm.Monoecious - This means one originating plant. Two sexes on one plant.Dioecious – Two sexes on two different plants. This means two originating plant. Ex. The holly – The holly berries are produced my females.
