oosphere's Usage Examples:

The oogonia, unlike the Peronosporaceae, contain more than one oosphere.

Fertilized egg with the central uninucleate cell (o) surrounded by the oosphere and the fertilizing periplasm (p).

We thus have a process of "multiple fertilization"; the oosphere really represents a large From Strasburger's Lehrbuch der Botanik, by permission of Gustav Fischer.

In Cystopus Bliti the oosphere contains numerous nuclei, and all the male nuclei from the antheridium pass into it, the male and female nuclei then fusing in pairs.

The contents of the antheridium are not set free, but that organ penetrates the oogonium by means of a narrow outgrowth, the fertilizing tube, and a male nucleus then passes over into the single oosphere, which at first multinucleate becomes uninucleate before fertilization.

Mycelium present, antheridia with antherozoids, oogonium with single oosphere: Monoblepharidaceae.

os, Oosphere.

In some cases the region where the penetration of the male organ takes place is indicated on the oosphere by a hyaline receptive spot (Oedogonium, Vaucheria, 'c.), or by a receptive papilla consisting of hyaline cytoplasm (Peronosporeae).

The eggcell or oosphere is a large cell containing a single large nucleus, and in the green plants the rudiments of plastids.

cell, which is non-motile, is carried to the oosphere by means of a pollen tube.
