Talk about steps of bryopsida sexual reproduction

Flagellated sperm cells travel to a neighboring plant via a water droplet and are chemically attracted to the entrance of the archegonium. Fertilization occurs when one of the sperm cells fuses with the egg (oogamy). The diploid zygote formed as a result of fertilization grows into a multicellular embryo by mitosis, and matures into a moss sporophyte. The embryonic sporophyte develops within the archegonium, and the mature sporophyte stays attached to the female gametophyte throughout its existence. The sporophyte is not photosynthetic. Thus both the embryo and the mature sporophyte are nourished by the photosynthetic gametophyte. Meiosis of the sporocytes (spore mother cells), within the capsule of the sporophyte, forms haploid spores. When the spores are mature, the capsule opens and the spores are dispersed by wind or rain. If a moss spore lands on a suitable spot, it germinates and grows into a filamentous thread of cells called protonema. The protonema forms buds, each of which grows into a leafy gametophyte plant, and the life cycle continues.
