In an angiosperm male plant is diploid
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.

WebJun 8, 2024 · Inside the anthers’ microsporangia, male gametophytes divide by meiosis to generate haploid microspores, which, in turn, undergo mitosis and give rise to pollen … WebApr 9, 2024 · Plants have two distinct stages in their lifecycle: the gametophyte stage and the sporophyte stage. The haploid gametophyte produces the male and female gametes by mitosis in distinct multicellular structures. Fusion of the male and females gametes forms the diploid zygote, which develops into the sporophyte.
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
