general plant life cycle is represented by the diagram in Figure below. From the figure, you can see that the diploid sporophyte has a structure called a sporangium (plural, sporangia) that undergoes meiosis to form haploid spores. A spore develops into a haploid gametophyte.
The life cycle corresponds to the ferns or pteridophyte because these plants have a two-phase life cycle, one of sporophyte and the other in gametophyte. These two phases are diploid and haploid. The diploid phase is asexual and the sexual phase is diploid.
The leaves of the fern have in their leaves structures called soros where the sporangia are, they th form the spores and are found through meiosis, when the spores are mature they fall to the ground and germinate in places of high humidity in this way a gametophyte with rhizoids originates It is anchored to the ground. Gametangios develop on the gametophyte. The male gametangios are called anteidios, and the feminine ones are called archegoniums. The female organs contain the ovocell and the male organs contain the sperm.
The sperm fertilize the ovocell and the junction forms a zygote.
The zygote grows and forms a sporophyte by mitosis, or cell division and the cycle is repeated
