Lub xub ntiag ntawm basidia yog ib qho ntawm cov yam ntxwv tseem ceeb ntawm Basidiomycota Ib basidium feem ntau dais plaub qhov kev sib deev hu ua basidiospores; Qee zaum tus lej yuav yog ob lossis txawm yim. Nyob rau hauv ib tug raug basidium, txhua basidiospore yog yug nyob rau hauv lub ntsis ntawm ib tug nqaim prong los yog horn hu ua sterigma (pl.

Pob basidia tsim cov spores?

Lub phylum Basidiomycota yog ib pawg ntawm cov kab mob uas tshwm sim los ntawm kev tsim cov hlwb tshwj xeeb-zoo li lub hlwb, hu ua basidia, thaum yug me nyuam. Lub basidia ib txwm tsim plaub haploid spores, hu ua basidiospores. Qee tus Basidiomycota yug me nyuam asexually, thiab qee qhov me me me me.

hom fungi twg tsim spores ntawm basidia?

Basidiomycota yog cov fungi filamentous tsim los ntawm hyphae (tshwj tsis yog rau basidiomycota-pob poov xab) thiab tsim kev sib deev los ntawm kev tsim tshwj xeeb club-zoo li lub hlwb kawg hu ua basidia uas feem ntau dais sab nraud meiospores (feem ntau yog plaub). Cov spores tshwj xeeb no hu ua basidiospores.

txheej txheem dab tsi tsim spores hauv basidia?

Nyob rau hauv lub basidium, nuclei ntawm ob hom sib txawv mating fuse (karyogamy), ua rau ib tug diploid zygote uas ces undergoes meiosis. Lub haploid nuclei tsiv mus rau hauv plaub chav sib txawv ntxiv rau basidium, thiab tom qab ntawd dhau los ua basidiospores.

Dab tsi yog lub luag haujlwm ntawm basidia?

Basidium, hauv cov kab mob (lub nceeg vaj Fungi), lub cev hauv cov tswv cuab ntawm phylum Basidiomycota (q.v.) uas dais lub cev tsim tawm kev sib deev hu ua basidiospores. Lub basidium ua haujlwm raws li qhov chaw ntawm karyogamy thiab meiosis, ua haujlwm los ntawm kev sib deev hlwb fuse, pauv cov khoom siv nuclear, thiab faib ua cov basidiospores
