Sorry, no etymologies found.
Last one there's a rotten egg, and as if being a moldy oospore weren't enough, they'll also miss out on a potentially rich stream of revenue from the portable video-palooza.
After being thus fertilized the contents of the sporangium acquire a peculiar oily appearance, of a beautiful emerald color, an exceedingly tough but transparent envelope is secreted, and thus is constituted the fully developed oospore, the beginner of a new generation of the plant.
Its brilliant hue has faded and changed to a reddish brown, but after a rest of about three months (according to Pringsheim, who seems to be the only one who has ever followed the process of oospore formation entirely through), the spore suddenly assumes its original vivid hue and germinates into a young
After the production of this oospore the parent filament gradually loses its vitality and slowly decays.
After impregnation the fertilized oosphere immediately surrounds itself with a cell-wall and becomes the oospore which by a process of growth forms the embryo of the new plant.
Reproduction from an oospore formed by the combination of two sexual cells.
But the asexual generation derived from the oospore only for a short while remains in connection with the prothallium, which, of course, answers to the leafy portion of the moss.
The elutant was centrifugated at 3000 rpm for 10 min to pellet the oospores. β-glucuronidase was added to the oospore and water suspension to a final concentration of 2000 U / ml.
From the union of the protoplasm of the last two, there results in each case a single oospore.
Hartog ( '92) states that in Saproleg - nia the reduction of the number of nuclei to that of the future oospheres is completed as early as the beginning of the foimation of the ongins, while in Acklya it may be delayed until the young oospore.
