Detailed explanation-1: -The gametophyte is the dominant life phase in the Bryophytes. The gametophyte produces structures known as antheridia and archegonia, which produce the male and female gametes respectively. Collectively these structures are known as gametangia.
Detailed explanation-2: -In plants, the gametophyte generation is one that which begins with a spore that is haploid (n). The spore undergoes series of mitotic divisions to give rise to a gametophyte. A gametophyte is a haploid multicellular plant form. It would therefore have only one set of chromosomes.
Detailed explanation-3: -In 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.
