Z explain the steps involved in fertilization, (syngamy and triple fusion), embryo development, endosperm development, formation of seed;Reproduction in flowering plants begins with pollination, the transfer of pollen from anther to stigma on the same flower or to the stigma of another flower on the same plant (selfpollination) or from the anther on one plant to the stigma of another plant (crosspollination) Once the pollen grain lodges on the stigma, a pollen tube grows from the pollen grain to an ovuleIn flowering plants the male gametes are inside the pollen grains and female gametes are inside the ovules (discussed later) During sexual reproduction the gametes fuse together at fertilisation and form zygote Zygote divides to form an embryo which may grow into a new individual plant The offspring shows genetic variations
