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: -In moss sporophyte plant, spores are produced in a capsular structure known as sporangium. The sporangium is attached to the gametophyte and obtains its nutrition with the help of a small stalk known as seta (Figure 2).

Detailed explanation-3: -Sporophytes are plant generations that produce spores. Spores are produced by algae, bryophytes, angiosperms, and gymnosperms. A spore is a tiny structure that, after germination, gives rise to a new plant.
