BOTANY

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). The male gametes in these plants swim through the water to reach the female gamete.

Detailed explanation-3: -Each sporocyte will undergo meiosis and thus produce 4 haploid spores. These are single-celled structures and are haploid, and it begins to germinate. This results in the formation of gametophyte, a plant form that consists of gametangia and produces gametes.
