WitrynaThe diploid sporophyte gives rise to haploid spores through meiosis. The process is related to sperm and egg production in animals and plants. The next step involves the formation of prothallus (gametophyte) by mitosis. Each prothallus contains haploid chromosomes and produces gametes. The sporophyte will consist of frond and … WitrynaThe spores germinate to form the haploid gametophyte. In seedless vascular plants, the gametophyte is small but photosynthetic; it bears gametangia – antheridia and archegonia that produce sperm and eggs, respectively. During fertilization, the sperm swim to the egg resulting in a diploid zygote. Witryna28 kwi 2024 · The diploid sporophyte produces haploid spores (by meiosis) in specialized sacs called sporangia.
