Sporic or diplohaplontic life cycle. A diploid (2n) sporophyte undergoes meiosis to produce haploid (1n) reproductive cells, often called spores. Haploid cells undergo mitosis to produce a gametophyte. The gametophyte produces haploid gametes which fuse to form a diploid zygotic sporophyte

Sporic meiosis
Explanation:
- In sporic meiosis (also commonly known as intermediary meiosis), the division of the zygote takes place mitotically in order to generate multicellular diploid sporophyte
- Sporic meiosis, has mitosis in two stages, both the diploid and haploid stages, termed diplobiontic.
- Sporic meiosis occurs in all plants except thallophyta. In sporic meiosis, the division by mitosis happens to create a multicellular diploid organism, the sporophyte.
- Some of the cells of the sporophite then produce spores through a sporic meiosis.
- In this case, the meiosis is sporic (because it produces spores). The spores then produce a haploid gametophyte which, in turn, will produce the gametes through mitosis.
