    Study Notes

    ### Metagenesis in Ferns

    • Metagenesis is a life cycle that involves two alternating phases: sporophyte and gametophyte.
    • In ferns, the sporophyte, which is diploid, produces spores through meiosis.
    • Spores germinate into the gametophyte, which is haploid.
    • The gametophyte produces gametes (sperm and egg) through mitosis.
    • Fertilization of the gametes produces a zygote.
    • The zygote develops into a new sporophyte, completing the cycle.

    ### Characteristics of Mosses

    • Mosses have a dominant gametophyte stage in their life cycle.
    • The gametophyte is photosynthetic and relatively large compared to the sporophyte.
    • The sporophyte is dependent on the gametophyte for nutrition and support, growing directly out of the gametophyte.
    • Mosses commonly inhabit moist, shady environments.
