(13) Enzymes of polyol metabolism were studied in basidiospore germination of Schizophyllum commune during periods of in vivo arabitol and mannitol pool depletion (growth on glucose-asparagine) and during their subsequent synthesis (growth on acetate-NH+4).

(20) These are Cladosporium, Basidiospores, Aspergillus, and Alternaria-Penicillin families.
Spore
Definition:
(n.) One of the minute grains in flowerless plants, which are analogous to seeds, as serving to reproduce the species.
(n.) An embryo sac or embryonal vesicle in the ovules of flowering plants.
(n.) A minute grain or germ; a small, round or ovoid body, formed in certain organisms, and by germination giving rise to a new organism; as, the reproductive spores of bacteria, etc.
(n.) One of the parts formed by fission in certain Protozoa. See Spore formation, belw.
