Haploid in which non-spore haploid cells are produced.

Those reproductive structures produced by gametangia of course are gametes, which in turn are produced by gametophytes. Contrast with sporangia. Depending on the gamete produced, gametangia can be distinguished into antheridia versus archegonia.

Note that both plants and , etc., possess gametangia, i.e,. the reproductive structure that produces their gametes (if present). Note that in land plants the gametangia are not associated with meiosis" since the gametes of plants are produced mitotically.
