a treatsie on the british freshwater alge
septum appears and cuts off the swollen end as a zoogonidangium. The contents
of this gonidangium, which are of a rich green colour, gradually become rounded
off, forming an oval zoogonidium of large size. The whole surface of the ...
During the development of the zoogonidium the growing apex of a filament
assumes a club-shaped form and becomes of an intense green colour, after
which a transverse septum appears and the swollen end is cut off as a
zoogonidangium.
Published figures generally show the cilia about £ to J as long as the body of the
zoogonidium. The length of the cilia of the zoogonidia of O. cryptoporum (Pig 1, G
), however, were observed to be f to £ of the body-length, as the measurements ...

Introduction to Elementary Practical Biology
Treat a moving zoogonidium with two per cent, salt solution to plasmolyze it. Do
you find a cell- wall apparent ? Treat in like manner a zoogonidium which has
come to rest, and compare it with the first. Try to find filaments in which the
formation ...

A good illustration of this is afforded by the development of the zoogonidium of
CEdogonium . The cytoplasmic contents of an ordinary cell of the filament

Text-book of Botany: Morphological and Physiological
In other species, as V. sessilis, sericea, and piloboloides, the contents of a
branch become separated and contract, and force themselves out as a
zoogonidium through a crevice at the extremity. The motion of the zoogonidia
lasts, in V. sericea, ...

The protoplasmic contents of each cell form a single rounded mass—the
Zoogonidium, which escapes by a fissure in the wall, and revolves and
progresses by means of the band of cilia. Fig. 9. Germination of Zoogonidium. .
