WebThe sporangium in the ovary (where the female gametophyte will be formed) is called the megasporangium. Diploid microspore mother cells in the microsporangium and diploid megaspore mother cells in the megasporangium divide by meiosis to form four haploid micro- or mega- spores. These spores initiate the gametophyte phase. WebAre they haploid or diploid? 2. Do the spores belong to the gametophyte or sporophyte generation? EXPT 2 1. Study the fresh flower.
