Detailed explanation-1: -The male sex organ, the antheridium, is a saclike structure made up of a jacket of sterile cells one cell thick; it encloses many cells, each of which, when mature, produces one sperm. The antheridium is usually attached to the gametophyte by a slender stalk.

Detailed explanation-2: -Male sex organs known as antheridia and female sex organs, which are referred to as archegonia, are typically located at the tips of the main shoots of gametophyte mosses.

Detailed explanation-3: -The antheridium is the male gametophyte and produces sperm cells (male gametes). The antheridium will produce numerous sperm for fertilization. The archegonia are the female gametophyte and will produce egg cells (female gametes).

Detailed explanation-4: -Male gametophytes develop reproductive structures called antheridia (singular, antheridium) that produce sperm by mitosis. Female gametophytes develop archegonia (singular, archegonium) that produce eggs by mitosis.

Detailed explanation-5: -Gametophytes are the gamete-producing bryophyte that forms the main part of the plant body. Archegonia is the female sex organ present in the gametophyte which is produced at the leafy apex in sexual reproduction. Antheridia is the male sex organ present in the gametophyte which is also produced at the apex.
