Gametophore

from Wikipedia, the free encyclopedia
Single gametophore of the deciduous moss Physcomitrella patens

The technical term gametophore or Gametangiophor (of gametangium and Greek. Φορά, phor ; dt "worn".); German "Gametangienträger", or "Gametangienstand", is in mosses and fern plants (Archegoniaten) the name for the carrier of the genital organs of the archegonia and the antheridia . If both archegonia and antheridia are on the same plant, they are called monoecious . If there are both male and female plants, they are called diocesan .

In deciduous mosses , the gametophore is the actual moss plant, which is divided into stems and leaves (see also “ Thallus ”). It represents the adult form of the haploid gametophyte and develops from its juvenile form, the protonema , under the influence of phytohormones (especially cytokinin ). While the filamentous protonema grows with a single-edged apex cell, the gametophore has a three-edged apex cell.
