A variant of it occurs in jellyfish and flatworms, and it is also known as metagenesis or heterogenesis. Coined by Wilhelm Hofmeister, it begins when meiosis takes place in specialized spore mother cells to produce haploid spores, which divide by mitosis to produce the gametophyte. Also occurring in brown, red, and green algae, for 10 points, give the term for the process by which multicellular haploid and diploid stages make up different parts of a plant's life cycle, best known for its role in fern reproduction.
