Botany for Degree Students Part-III: Bryophyta
It consists of a ring of cells and surmounts the archegonial base. It is called the
perigynium or pseudoperianth. The formation of the perigynium is stimulated after
fertilization. The ventral canal cell and the neck canal cells degenerate at ...

All superficial cells at the micropylar end of the female gametophyte have the
capacity to develop into archegonia, but only a few cells differentiate into
archegonial initials. The number of archegonial initials varies in different species;

(a) Archegonial branch. The archegonial branches arise laterally at the base of

Archegonium — The archegonium develops from a single celled archegonial
initial which grows and projects above the surface of thallus. It then divides
transversely into an outer or upper cell and a lower or basal cell. The lower cell or
basal ...
As in Pinaceae the archegonial cytoplasm is composed of numerous cytoplasmic
inclusions. The enclosed cytoplasm, unlike Pinaceae, represents a smaller
fraction of the egg cytoplasm. It shows nodules of dense cytoplasm with crescent-

Usually 2-6 cells in the micropylar region of the female gametophyte differentiate
into archegonial initials. In Dioon edule up to 10 archegonial cells are formed
and in Microcycas more than 100 archegonial initials differentiate some of them
