Spcrmatization: It is brought about by a spermatium and a receptive hypha of
different strains. All spcrmaua in a single spermogonium carry the same strains.
At the time of the extrusion of spermatia through the ostiole, the spermogonium ...
The spermatia of the Rhodophyceae are spherical or oblong cells produced in
spermatangia, a single spermatium being formed in a sper- matangium and then
released, leaving the empty sporangium (Fig. 4.19). The spermatangia (Fig.

Seaweed Ecology and Physiology
Each spermatium represents a sequential stage from a to f. (a) Spermatium with a
prophase nucleus binds to the surface of a trichogyne; (b) a few minutes after
gamete binding, the spermatium develops small vacuoles (arrow) at the cell ...

Imperial Botanical Conference
In all the higher Florideae where fertilisation is reported, no nuclear division has
been seen, and the inference is that the so-called chromosomes in the ripe
spermatium represent initial stages of an abortive attempt at nuclear division
which ...

Lectures on the Physiology of Plants
The spermatium (anthero- zoid) is brought passively into contact with the
trichogyne ; complete fusion takes place so that the contents of the spermatium
pass into the trichogyne. When this has occurred the trichogyne withers and
changes ...
The contents of each spermatangium develop into a single non- flagellate, non-
motile male gamete, called spermatium. Mature spermatangium: It is a unicellular
, uninucleate, colourless, spherical structure surrounded by a thick wall made up
...

Cryptogams: Algae, Bryophyta and Pterldophyta
The uninucleate protoplast of the spermatangium gets transformed into a single
spermatium. Each spermatium is spherical, unicellular and non- flagellate. The
spermatium is released by the rupture of the spermatangial wall. After the release
...

Fundamentals of Botany Vol-1
Each spermatangium produces single male reproductive cell called the
spermatium. The spermatia are liberated by the rupture spermatangial wall.
Sometimes, a new spermatangium may proliferate within the old spermatangial
wall after the ...

Fungi: Ascomycetes, Ustilaginales, Uredinales
In Ascobolus carbonarius, a small, spermatium-like, attached cell (the male
conidium of Dodge) has been observed in association with the tip of the
trichogyne; somewhat similar attached cells have been seen in Collema
pulposum; in other ...
