Description: This illustration shows the germination of the gametospore: A, section of a mature archegonium with canal cells dissolved, thus forming a passageway to the large female gamete, g. B, sectional view of base of archegonium, showing the germinating gametospore in two-cell stage. The perianth, p, is seen growing up about the archegonium. C, later stage in growth of the gametospore. The lower cell shown in B is forming stalk cells, while the outer cell has produced densely granular cells that will later by further division form spore mother cells and elaters.
