Each carpogonium is present at the top of a short 2- 5-celled carpogonial filament
. The carpogonium is a Mask-shaped body, having a basal swollen portion drawn
out into a long tubular neck-like trichogyne. Uninucleate female gamete is ...

Synopsis of Biological Data on the Seaweed Genera Gelidium ...
The carpogonium continues to elongate and the apical prolongation penetrates
the surfaces of the thallus forming a trichogyne. During the development of the
carpogonium, a number of conical primordia are formed from and around the cell
...

Green Plants: Their Origin and Diversity
The coming together of the spermatium and carpogonium appears to depend
entirely upon water currents. Following fertilization the carpogonium develops
into a carposporangium containing a single diploid carpospore. This gives rise to
a ...
Peter R. Bell, Alan R. Hemsley, 2000
carpogonium fuses to form a multinucleate fusion cell. Papenfuss (1966)
recognizes two types of auxiliary cells, nutritive and generative. Nutritive auxiliary
cells provide nutrients for the developing carposporophyte, whereas generative ...

Cryptogams: Algae, Bryophyta and Pterldophyta
The female sex organ is called carpogonium and is unicellular with a long neck
called trichogyne. 17. The sexual reproduction in Florideae is characterised by : (

An Introduction to the Study of Algae
Each carpogonium possesses a short neck or trichogyne (the long neck of
Coleochaete scutata being an exception) the top of which bursts when the
carpogonium is mature. In the disk forms the carpogonia originate as terminal Fig
. 50.

The development of the female gametangium (carpogonium) proceeds from a
pericentral cell of the main branch, which develops into a filament of four cells (
carpogonium filament). The end cell becomes the carpogonium, which develops
into ...

The Diversity and Evolution of Plants
Development of the carpogonium typically takes place in a cavity on the thallus
surface, usually near the margin, called a conceptacle (Figure 4-3). In most
species of red seaweeds, the zygote migrates through a secondary pit
connection into ...
