| Notwithstanding their general similarity, the archegonia of mosses differ externally from antheridia in having a longer neck and longer stalk. |
| Since the asexual gametophyte does not form antheridia or archegonia, crosses to confirm its genotype could not be performed. |
| Meiosis occurs just before mating in well-differentiated oogonia and antheridia. |
| Studies on development of antheridia and antheridial dehiscence have been conducted by Davie and Hartman. |
| On their release from the antheridia, the antherozoids must then swim through surface water to fertilize neighbouring egg cells. |
| Each antheridial chamber incorporates several antheridia, all of which are developed from one antheridial initial. |
