Bryophytes
Lifecycle
When a spore lands on a ground where it can germinate, it grows into a mass of green filaments called Protonemia. The Protonemia grows and builds rhizoids that grow into the ground and buds (if land plant) that grow into the air until it reaches the gametophyte stage. The female archegonium and the male antheridium (gametophytes) build either haploid sperm or egg. The Sperm enters the female Archegonium and fertilizes the egg to produce a diploid zygote. That is the beginning of the sporophyte stage of the life cycle. It grows directly out of the body of the female gametophyte. The mature sporophyte is a long stalk ending in a capsule containing the new haploid spores produced by meiosis.
Bryophytes Examples
Mosses, Liverworts and Hornworts
Mosses, Liverworts and Hornworts are "non-vascular plants" (no xylem & phloem) and its lifecycle is dominated by the haploid gametophyte stage which lacks vascular tissues. Since they have no true roots, they use rhizoids for stabilization. For fertilization they rely on a small film of water so that the flagelled sperm from the antheridium can swim over to the archegonium to fertilize its egg.
