Detailed explanation-1: -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-2: -Diploid sporophyte cells undergo meiosis to produce haploid spores. Each spore goes through mitotic divisions to yield a multicellular, haploid gametophyte.

Detailed explanation-3: -The sporophyte produces spores (hence the name) by meiosis, a process also known as “reduction division” that reduces the number of chromosomes in each spore mother cell by half. The resulting meiospores develop into a gametophyte.

Detailed explanation-4: -The haploid phase of the plant is called the gametophyte and the diploid phase of the plant is known as the sporophyte. The sporophyte generates spore in the plants whereas the gametophyte generates the gametes in the plants.
