antheridiophore in some liverworts, a stalk that bears antheridia embedded on an elevated and expanded tip.
The male parts of the flower are termed the anthers. They produce pollen, which contains the male gametes (sperm). The female parts of the flower are the stigma, style, and ovary. The egg (female gamete) is produced in the ovary.
The transfer of pollen from the anther to the female stigma is termed pollination. This is accomplished by a variety of methods. Entomophyly is the transfer of pollen by an insect. Anemophyly is the transfer of pollen by wind.
Transfer of pollen (pollination) from the anther of the flower of one plant to the stigma of the flower of a genetically different plant.
pollination - the transfer of pollen from the male anther to the female stigma of a flower.
Transfer of pollen (pollination) from the anther of a flower to the stigma of the same flower or sometimes to that of a genetically identical flower (as of the same plant or clone).
These did not appear to produce antheridia. Nonetheless, a subsequent generation of tetraploid sporophytes was produced. When grown in the lab, the tetraploid sporophytes appear to be less vigorous than the normal diploid sporophytes.
