#gametophyte structure
- Androgametophore — A specialized anatomical structure or bearing axis (found in certain lower plants, such as mosses or liverworts) that structurally supports the male reproductive organs (antheridia or androgametangia). This morphological support optimizes the spatial positioning of the male gametophyte, facilitating the efficient release and dispersal of flagellated sperm cells in the presence of water.
- Antheridiophore — A specialized structural formation, having the appearance of a stalk, branch, or erect support, which bears the antheridia (male reproductive organs) in some lower avascular plants, such as liverworts of the order Marchantiales. This structural support serves the ecological role of elevating the male organs above the thallus, facilitating the efficient dispersal of plant spermatozoa via raindrops or dew.
