The androspore cuts off two primary prothallial cells by periclinal divisions, the
large cell is called the antheridial initial cell. • The primary prothallial cells may
divide further to form secondary prothallial cells. • The antheridial initial divides to

Botany For Degree Gymnosperm (M.E.)
The pollen grain nucleus divides into two particular primary prothallial cells by
periclinal divisions. The larger cell functions as an antheridial initial and divides
periclinally to form the generative and tube cells. The primary prothallial cells
may ...

Malegametophyte: The microspore nucleus cuts off two prothallial cells in
succession (Fig. 9.8B, C). The pollen is shed at the four-celled stage carrying two
prothallial cells, one antheridial cell and one tube cell (Fig. 9.8D). Of the two
prothallial ...

Plants: Diversity and Evolution
In cycads the male gametophyte is a single vegetative cell called the prothallial
cell, and an antheridial cell. The latter divides to produce a tube nucleus and a
generative cell. In its turn the generative cell divides to produce a stalk and body

... and intine separate to form the sacci. Some taxa have two sacci and others
have three sacci. Once the microspore has formed its sacci, its central cell divides
unequally twice, producing two small prothallial cells and a larger antheridial ...

PATTERNS OF SPORE GERMINATION The germination of spores in
Lycopodium and Equisetum is bipolar, resulting in the formation of a small
rhizoidal cell and a larger prothallial cell. The rhizoidal cell fails to form rhizoid in
Lycopodium.

The nucleus divides and a first prothallial cell is cut against the inline. A second
prothallial cell is cut off from the other cell adjacent to the first prothallial cell. The
two prothallial cells disorganise. The remaining cell is called the antheridial cell.

The Evolution of the Land Plants (Embryophyta)
In the Pinaceae, the Araucariaceae, and the Podocarpaceae sterile prothallial
cells are cut off before the formation of the generative cell. In Pinus there are
usually two prothallial cells which are disorganized before the generative cell is
formed ...
