Pollen grains fall on stigma of flowers and it forms pollen tube which runs along with style after chemotropism. Nucleus of pollen grain divides itself into 2 haploid male gamate. One fuses with the egg cell and forms diploid cell and it develops into seed. Other gamate fuses with diploid polar nuclei and forms triploid cell which serves as food for zygote or seed. Ovary develops into fruit and gives protection and food.
