Detailed explanation-1: -Diploid sporophyte cells undergo meiosis to produce haploid spores. Each spore goes through mitotic divisions to yield a multicellular, haploid gametophyte . Mitotic divisions within the gametophyte are required to produce the gametes. The diploid sporophyte results from the fusion of two gametes.

Detailed explanation-2: -In the sporophyte phase a diploid (having two sets of chromosomes) plant body grows and eventually produces spores through meiosis. These spores divide mitotically to produce haploid (having a single set of chromosomes) gamete-producing bodies called gametophytes.

Detailed explanation-3: -In plants, alternation of generations exists, where the members have haploid and diploid phases. The plant’s haploid phase is called gametophyte and the diploid phase is called the sporophyte.

Detailed explanation-4: -A sporophyte is a diploid multicellular stage in the life cycle of plant including Pteridophytes which develops from the zygote produced when a haploid egg cell is fertilized by a haploid sperm and each sporophyte cell therefore has a double set of chromosomes.

Detailed explanation-5: -The sporophyte is the diploid generation of a plant that produces haploid spores via meiotic divisions. In bryophytes, the sporophytes are always unbranched and produce a single sporangium (spore-producing capsule), but each gametophyte can give rise to several sporophytes at once.
