The parent also contains antheridia which produce sperm and an oogonium which produces the egg. |
In the rotting tissues branches of the older mycelium similarly swell up and form antheridia and oogonia. |
Studies on development of antheridia and antheridial dehiscence have been conducted by Davie and Hartman. |
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. |
Each antheridial chamber incorporates several antheridia, all of which are developed from one antheridial initial. |
