Web- The sporophyte is diploid (2N), develops from the fusion of haploid male and female gametes and through meiosis produces haploid spores. The green, leafy generation of a given plant is called the dominant generation. For the bryophytes, the gametophyte is the dominant generation (Fig. 9.19 pg. 9-16 & Fig. 22.12 pg. 22-17). WebThe result is a multi-cellular haploid organism, called the gametophyte (because it produces gametes at maturity). When it reaches maturity, the gametophyte produces one or more gametangia (singular: …
WebApr 9, 2024 · The gametophyte has the reproductive organs which undergo mitosis to form haploid gametes. The gametes fertilize to form a haploid zygote which matures into a mature sporophyte.
