Life cycle of a bryophyte.
- Spores develop into haploid protonemata.
- Protonema produce "buds" that undergo mitosis.
- Buds develop into gametophyte
bearing antheridia or archegonia.
- Sperm swims
to egg in archegonium.
- Fertilized diploid zygote develops into sporophyte embryo.
- Sporophyte emerges from the archegonium.
- The small sporophyte
is dependent on the large
gametophyte.
- Spores develop by meiosis in sporangium whose teethlike peristome
regulates spore dispersal.
