Among these basidia and sterile cells will frequently be seen an overgrown bladder-like sterile basidium which projects beyond the rest of the hymenium, and whose use is not as yet fully known.
Each projection or sterigma soon swells at its extremity into a bladder-like body, the young spore, and, as they enlarge, the protoplasm of the basidium is passed into them.
When the basidium which bears mature spores is still well charged with granular matter, it may be presumed that the production of a second or third series of spores is quite possible.
Life-history always very simple, no well-marked alternation of generations; basidium borne directly on the mycelium.
Petersii has a transversely divided basidium as in Auriculariaceae, but the basidia are surrounded with a peridium-like sheath.
The first named contains a small number of forms with the basidium divided like the promycelium of the Uredineae.
Formerly, before the relationship of promycelium and basidium were understood, the Uredineae were considered as quite independent of the Basidiomycetes.
During the tetrad division in the basidiumnuclear reduction occurs.
There is also a further reduction in that the basidium is not derived from a teleutospore but is borne directly on the mycelium.
C, A basidium before the four nuclei derived from the secondary nucleus of the basidiumhave passed into the four basidiospores.
The basidium is a unicellular or multicellular structure from which four basidiospores arise as outgrowths; it starts as a binucleate structure, but soon, like the ascus, becomes uninucleate by the fusion of the two nuclei.
Between the nuclear association and the nuclear fusion in the basidium many thousands of cell generations may be intercalated.
In F, a basidiumis shown, with the young spores just forming.
All of the group are characterized by the production of spores at the top of special cells known as basidia,[8] the number produced upon a single basidium varying from a single one to several.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "basidium" in a variety of sentences. We hope that you will now be able to make sentences using this word.
