Fungus (Rhizopus oligosporus) (haploid organism) Fern (Humata tyermanii) (diploid sporophyte) African fish eagle (Haliaeetus vocifer) (diploid organism) Mature organism (n) Spores (n) Gametes Male (n) Female (n) HAPLOID (n) DIPLOID (2n) Meiosis Fertilization Zygote (2n) In the haplontic life cycle, the mature organism is haploid and the zygote is the only diploid stage. Gametophyte (n) Spore (n) Gametes Male (n) Female (n) HAPLOID (n) DIPLOID (2n) Meiosis Fertilization Zygote (2n) Sporophyte (2n) In alternation of generations, the organism passes through haploid and diploid stages that are both multicellular. Gametes Male (n) Female (n) Meiosis Fertilization HAPLOID (n) DIPLOID (2n) Zygote (2n) Mature organism (2n) In the diplontic life cycle, the organism is diploid and the gametes are the only haploid stage. Using the information on ploidy of different life stages in the organisms above, and based on what you know about the effects of mitosis and meiosis on ploidy, which kind of cell division is responsible for the production of gametes in the three life cycles illustrated above? Mitosis or Meiosis: Fungi produce gametes via: Plants produce gametes via: Animals produce gametes via:
