TWO STAGES. “In angiosperms the diploid sporophyte is the dominant stage and the haploid gametophyte is completely dependent upon the sporophyte. The flower is part of the sporophyte: it is diploid and through meiosis will produce spores that will undergo mitosis to form gametes. The anthers will produce haploid microspores. These will undergo mitosis and differentiate to form the pollen grains, each of which carries two sperm. The ovules will produce haploid megaspores.”
