Detailed explanation-1: -The sporangium undergoes meiosis and forms haploid spores. The spore develops into a gametophyte which is haploid in nature. The gametophyte has the reproductive organs which undergo mitosis to form haploid gametes. The gametes fertilize to form a haploid zygote which matures into a mature sporophyte.

Detailed explanation-2: -Alternation of generations means that plants alternate between two different life stages, or generations, in their life cycle; a haploid stage called gametophyte and a diploid stage called sporophyte.

Detailed explanation-3: -Gametophytes Are the Haploid Stage The gametophyte stage, or generation in the alternation of generations life cycle, is the haploid (n) stage. The gametophyte stage can also be thought of as the sexual stage because it will produce the gametes, or sex cells. This stage only has one set of chromosomes.

Detailed explanation-4: -gametophytes. …the gametophyte phase, which is haploid (having a single set of chromosomes), male and female organs (gametangia) develop and produce eggs and sperm (gametes) through simple mitosis for sexual reproduction.

Detailed explanation-5: -Plants have two distinct stages in their lifecycle: the gametophyte stage and the sporophyte stage. The haploid gametophyte produces the male and female gametes by mitosis in distinct multicellular structures. Fusion of the male and females gametes forms the diploid zygote, which develops into the sporophyte.
