WebIf the female plant is tetraploid, then the central cell of the embryo sac, which is a fused polar nuclei, will also be tetraploid. Since the male angiosperm is diploid, hence the male … WebFertilization in plants occurs when haploid gametes meet to create a diploid zygote, which develops into an embryo. In gymnosperms (conifers) and angiosperms (flowering plants), the meeting of the gametes occurs in the …

WebAngiosperms: A group of flowering plants that produce seeds enclosed in an ovary, which matures into a fruit. Gymnosperms and angiosperms have reduced gametophytes that are dependent on the sporophyte, while bryophytes and seedless vascular plants have dominant gametophytes. In gymnosperms and angiosperms, the male gametophyte develops within … WebInside the anther’s microsporangia, male sporocytes divide by meiosis to generate haploid microspores, which, in turn, undergo mitosis and give rise to pollen grains. Each pollen grain contains two cells: one generative cell that will divide into two sperm and a second cell that will become the pollen tube cell. Art Connection WebFusion of the male and females gametes forms the diploid zygote, which develops into the sporophyte. After reaching maturity, the diploid sporophyte produces spores by meiosis, … gcash to seabank transfer fee
