University Botany I : (Algae, Fungi, Bryophyta And Pteridophyta)
In Jungermanniales, there is further sterilization of the sporogenous tissue. In
Pellia, (Fig 5. IE) the sporophyte is differentiated into foot, seta and capsule. The
wall of the capsule is two to three layered. Inside the capsule, a mass of sterile ...

The Anther: Form, Function, and Phylogeny
Z.) is essentially constant, so most of the variation in pollen production arises
from changes in the number of archesporial initials and/or the number of pre-
meiotic mitoses of sporogenous cells. Thus, the number of microsporocytes (M) ...
William G. D'Arcy, Richard C. Keating,
1996
The sporogenous tissue results as a consequence of prolific meristematic activity
of specialized cells (archesporial cells), which originate as a single layer from
either of the two fundamental embryonic layers — amphithecium and
endothecium ...
The archesporial tissuedivides periclinally to form an outer primary parietal layer
and an inner primary sporogenous layer. The primary parietal layer undergoes
periclinal divisions to form a multilayered microsporangial wall, the innermost ...

Bryopsida (Musci) (a) Sphagnidae— Sphagnales Sphagnum (b) Bryidae— F
unariales F unaria The entire endothecium becomes the archesporium, and
forms the sporogenous tissue. The whole mass of endothecium forms the
archesporium ...

Competition Science Vision
In each lobe, commonly a row of hypoder- mal archesporial cells is differentiated
which form the archesporium of the anther. Each archesporial initial divides into
an outer primary parietal cell and an inner primary sporogenous cell.

morphology of angiosperms
of Angiosperms the primary sporogenous cell is the mother-cell. The only
possible exception to this is the case of such sporogenous masses as occur in
the ovules of Casuarina (Treub23), Carpinus (Miss Benson28), and Quercus
iConrad88).
John Merle Coulter And Charle Joseph Chamberlain,
1987

Botany For Degree Pteridophyta
3.16 C) reveals that it is partitioned into two sporogenous regions (Fig. 3.17 C, D).
The wall of the sporangium is made of three or four layers. There is no tapetum.
In a mature sporangium there is, however, breakdown of inner wall layers.
The sporogenous cells, in general, belong to differentiated sporogenous
filaments. Always multicellular, they are simple or branched and free or
anastomosed, depending on the species. In this case, they can form a loose
network or a kind of ...

cells) have ...
