Study Notes
###Â 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.
###Â 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.
