Green Plants: Their Origin and Diversity
With a few exceptions, the fossil record indicates that the most primitive forms of
land plants were probably all archegoniate. Notable amongst the likely
exceptions is Protosalvinia, an enigmatic Devonian plant (p. 93). Its structural and
...

Evolution of Primary Producers in the Sea
The archegoniate plant life history is derived from the zygote-dominant life history
by the insertion of mitotic divisions between the formation of the zygote and the
onset of meiosis, producing a separate vegetative plant that, because it produces
...

Whereas under conditions of better nutrition, the proportion of archegoniate
gametophytes increases. In long term cultures, and particularly when fertilization
is delayed, the archegoniate forms produce antheridia. Gametophytes of
Equisetum ...

The Ferns (filicales) Treated Comparatively with a View to ...
The reason for holding this opinion is that a comparison of Archegoniate with
Archegoniate is nearer than that of an Archegoniate with any Alga, and it is more
reliable because it leaves less scope for the slack joint of homoplasy. In Chapter
III ...

Likewise, bryophytes constitute the non-vascular archegoniate, whereas
pteridophytes and gymnosperms together form the group called vascular
archegoniate. 5. The gymnosperms, containing 'plants with unprotected seeds'
have rightly ...

Pteridology in perspective
During this 'equilibrium period' Ph. scolopendriumFBa' had an approximately
equal number of male and archegoniate gametophytes but all the other
populations were predominantly (i.e. 55-90%) male. Bisexual gametophytes
were detected ...

Alternation The most general characteristic of all is the alternating life-cycle, for
not only is this present in all Ferns, but also in all Archegoniate plants, while it
extends in some form or another to all plants that reproduce sexually. This is not
