Usage examples of antheridium.
Each antheridium or archegonium arises from a single cell, and while the mature structure is similar in the two groups, the development presents differences in liverworts and mosses.
Without entering into details it may be mentioned that in the mosses it proceeds both in the archegonium and antheridium by the segmentation of an apical cell, while this is not the case in the liverworts.
When mature the antheridium opens on being moistened and the spermatozoids become free in the water by the dissolution of the mucilaginous cell-walls enclosing them.
The small thallus bears the antheridia and archegonia, each of which is surrounded by a tubular involucre, on the upper surface of distinct individuals.
Their general similarity to the mature antheridia and archegonia of liverworts and the main difference in their development have been referred to.
The stalked globular antheridia are exceptional in being formed endogenously, and are situated in groups in special intercellular spaces.
