Qhov Tseem Ceeb Qhov txawv - Ascus vs Basidium
Ascomycetes thiab Basidiomycetes yog ob lub phyla loj hauv lub nceeg vaj fungi. Ob pawg sawv cev rau macrofungi thiab tsim cov txiv hmab txiv ntoo pom lub cev los yog sporophores kom dais spores. Spores yog qhov nruab nrab ntawm propagation ntawm cov fungi. Ascomycetes fungi tsim ib lub hnab-zoo li lub cell, bearing yim haploid spores hu ua ascospores thaum muaj kev sib deev. Cov qauv no hu ua ascus (plural: asci). Basidiomycetes tsim ib lub club-zoo li lub cell uas bears plaub protruded haploid spores hu ua basidiospores thaum muaj kev sib deev. Nws yog lub npe hu ua basidium (plural: basidia). Qhov sib txawv tseem ceeb ntawm ascus thiab basidium yog tias ascus tsim cov ascospores sab hauv thaum basidium tsim basidiospores sab nraud. Ob qho ascus thiab basidium yog cov qauv hauv microscopic.
Ascus yog dab tsi?
Ascomycetes yog ib qho phylum siab dua ntawm lub nceeg vaj fungi. Ascomycete yog ib lub phylum loj uas suav nrog ntau tshaj 44,00o hom tsiaj. Ascomycetes fungi yog paub zoo tias cov organic teeb meem decomposers hauv av. Lawv kuj tau siv hauv kev lag luam rau kev tsim tshuaj tua kab mob thiab cov organic acids. Cov kab mob no ua rau conidia thaum lub sij hawm yug me nyuam thiab ascospores thaum lawv yug me nyuam. Cov spores no germinate thiab tsim tshiab fungal hyphae mus txuas ntxiv lawv tiam.
Ascospores yog tsim nyob rau hauv ib lub cell ua me nyuam tshwj xeeb hu ua ascus. Ascus yog ib lub hnab zoo li lub cell uas muaj ascospores ntawm ascomycetes fungi. Nws yog cov qauv microscopic, uas tsim nyob rau hauv mycelial lev, thiab tsim ascospores sab hauv. Feem ntau, ascus muaj yim spores hauv nws. Li no, lub npe ascus tau muab rau cov qauv no. Qee cov ascomycetes fungi tsim plaub ascospores hauv ascus. Kuj tseem muaj hom tsiaj uas tsuas yog ib qho spore ib ascus thiab lwm yam nrog ntau tshaj li ib puas spores ib ascus. Spore naj npawb nyob rau hauv ascus hloov nrog fungal hom. Kev tsim cov ascus los yog asci yog ib qho tseem ceeb yam ntxwv uas distinguishes ascomycetes los ntawm lwm yam fungi. Ascospores thiab asci yog tshwj xeeb rau ascomycetes. Yog li cov kab mob ascomycetes tau yooj yim txheeb xyuas los ntawm qhov muaj asci hauv lawv cov mycelium.
Ascospores yog tsim los ntawm ob qhov kev faib meiotic ntawm diploid zygote nucleus. Thawj diploid nucleus faib ua plaub haploid nuclei los ntawm meiosis. Tom qab ntawd plaub lub nuclei sib npaug los ntawm mitosis los tsim yim ascospores.

Basidium yog dab tsi?
Basidiomycetes yog lwm lub cev ntawm lub nceeg vaj fungi uas belongs rau macrofungi siab dua. Muaj txog 25,000 hom basidiomycetes. Mushrooms thiab toadstools yog ob hom kev paub ntawm basidiomycetes. Basidiomycetes yog tus cwj pwm los ntawm kev tsim basidia. Basidium yog ib lub club-zoo li tus qauv uas tsim thaum muaj kev sib deev ntawm basidiomycetes. Nws yog cov qauv microscopic thiab tsim cov spores kev sib deev hu ua basidiospores. Basidia yog tsim nyob rau hauv hymenophore ntawm fruiting lub cev ntawm basidiomycetes. Lub xub ntiag ntawm basidia yog qhov tshwj xeeb rau basidiomycetes.
A basidium feem ntau tsim plaub basidiospores thiab qee zaus ob lossis yim spores. Txawm li cas los xij, nws tuaj yeem hloov nrog hom fungal. Basidia tsim cov qauv nqaim hu ua sterigmata. Ib qho basidium tsim plaub sterigmata, thiab ntawm qhov kawg ntawm sterigma, txhua basidiospore yog tsim los sab nraud. Nyob rau hauv lub xeev laus, basidiospores raug tso tawm los ntawm sterigmata mus rau ib puag ncig.

Summary – Ascus vs Basidium
Ascus yog cov kab mob sib deev-cov kabmob uas tsim tawm hauv ascomycete fungi. Nws yog cov qauv zoo li lub hnab uas muaj cov kab sib deev ntawm ascomycetes. Ascus yog tsim nyob rau hauv lub mycelium thiab yog ib tug microscopic qauv. Ascus feem ntau tsim yim ascospores sab hauv los ntawm ob lub meiotic cell faib ntawm diploid zygote. Basidium yog ib hom kab mob sib deev uas tsim tawm hauv basidiomycetes fungi. Nws yog ib lub club zoo li cov qauv uas muaj kev sib deev spores ntawm basidiomycetes. Basidium tsim plaub-feeb kev kwv yees hu ua sterigmata, thiab thaum kawg ntawm sterigmata, spores raug tsim tawm sab nraud. Qhov no yog qhov txawv ntawm ascus thiab basidium.
