单词 basidium
释义

Definition of basidium in English:

basidium

nounPlural basidia bəˈsɪdɪəmbəˈsɪdiəm
  • A microscopic club-shaped spore-bearing structure produced by certain fungi.

    Example sentencesExamples
    • These mated cells can grow in filamentous form with meiosis occurring at the terminal cell (basidium) of the hyphae.
    • Most importantly, monokaryotic hyphae can produce basidia and spores that are indistinguishable from sexually produced spores, except that they are all the same mating type.
    • Under continuous light, the maturation starts but stops halfway: meiosis in the basidia is arrested at prophase I, the stipe elongates only slightly, and the pileus does not expand.
    • After a few more days of incubation, the ends of some mycelia may enlarge and form basidia within which nuclear fusion and meiosis may occur.
    • The teliospores borne in these telia germinate to produce a basidium, which in turn produces basidiospores.

Origin

Mid 19th century: modern Latin, from Greek basidion, diminutive of basis (see basis).
