Qhov Tseem Ceeb Qhov txawv - Ascospore vs Basidiospore
Fungi yog ib pawg ntawm cov kab mob uas muaj cov kab mob phem thiab muaj txiaj ntsig. Lawv ua hauj lwm raws li lub ntsiab decomposers nyob rau hauv ib puag ncig. Fungi qhia txog kev sib deev thiab asexual reproductive mechanisms nyob rau hauv uas kev sib deev thiab asexual spores yog tsim los ua ib tug nruab nrab ntawm propagation. Fungi spores zoo ib yam li cov noob. Lawv germinate thiab muab nce mus rau ib tug tshiab fungal colony. Spores muaj cov qauv yooj yim. Txawm li cas los xij, muaj ntau hom fungal spores, uas txawv ntawm cov duab, xim, daim ntawv thiab qhov ntau thiab tsawg. Fungal spores muaj txiaj ntsig zoo hauv kev ua tus cwj pwm thiab kev sib txawv ntawm cov kab mob fungal. Asexual spores yog tsim nyob rau hauv sporangia los yog raws li conidia. Kev sib deev spores yog tsim los ntawm mating ntawm ob hom fungal hyphae. Muaj plaub yam loj ntawm kev sib deev spores hu ua oospores, zygospores, ascospores thiab basidiospores. Qhov sib txawv tseem ceeb ntawm ascospore thiab basidiospore yog tias ascospore yog ib qho kev sib deev tsim tawm ntawm cov kab mob fungal ascomycetes thaum basidiospore yog kev sib deev tsim tawm ntawm cov kab mob fungal basidiomycetes.
Ascospore yog dab tsi?
Ascospore yog kev sib deev fungal spore tsim los ntawm ascomycetes fungi. Ascospores yog tsim los ntawm kev sib deev kev sib deev ntawm ob hom ascomycetes fungi. Ascospores yog qhov tshwj xeeb rau ascomycetes vim lawv tau tsim hauv ascomycetes 'cov qauv tshwj xeeb microscopic hu ua ascus. Ascus yog ib tug cylindrical los yog kheej kheej qauv tsim nyob rau hauv lub hlwb los yog hyphae ntawm fungus. Ib yam ascus bears yim ascospores. Li no, nws tau muab lub npe ascus, xa mus rau cov qauv uas muaj yim spores. Muaj qee hom tsiaj uas tsim ib qho spore rau ascus thiab tseem muaj ntau tshaj li ib puas spores ib ascus.
Asci yog cov qauv sab hauv tsim nyob rau hauv qee yam ntawm cov txheej txheem ntawm ascomycetes. Yog li ntawd, ascospores kuj tsim nyob rau hauv tsis muaj protruding los ntawm hyphae. Kev tsim ntawm ascospores yog txheej txheem nyuaj uas ua raws li ob txoj haujlwm sib txuas ntawm tes: meiosis thiab mitosis. Lub diploid zygote faib los ntawm meiosis los tsim plaub haploid nuclei. Txhua ntawm plaub haploid nuclei duplicates los ntawm mitosis los tsim yim haploid hlwb hu ua ascospores hauv ib ascus.
Ascospores tuaj yeem ua xim lossis hyaline thiab tuaj yeem muaj cov duab sib txawv. Cov kab mob fungal uas tsim cov ascospores muaj xws li Penicillium spp, Aspergillus spp, Neurospora spp, poov xab, thiab lwm yam.

Basidiospore yog dab tsi?
Basidiospore yog ib qho kev sib deev uas tsim los ntawm basidiomycetes fungi. Basidiomycetes muaj xws li nceb, xeb, smuts thiab txee fungi, uas feem ntau hu ua club fungi. Basidiospores yog tshwj xeeb rau basidiomycetes vim lawv tau tsim nyob rau hauv basidiomycetes 'cov qauv tshwj xeeb hu ua basidia. Basidia yog cov kab mob tshwj xeeb uas tsim tawm los ntawm hyphae. Ib tug raug basidium muaj plaub haploid basidiospores. Cov spores no yog tsim los ntawm kev sib deev kev sib deev ntawm ob basidiomycetes fungi. Basidium tsim plaub sterigma ntawm nws qhov chaw, uas dais basidiospores.
Basidiospores dais txuas pegs hu ua hilar appendage hauv txhua qhov spore, uas tshwm sim vim qhov txuas nrog basidium; Nws tuaj yeem siv los txheeb xyuas basidiospores los ntawm lwm cov spores. Basidiospores yog asymmetrical thiab ib leeg celled. Lawv muaj cov duab sib txawv xws li kheej kheej mus rau oval mus rau oblong rau cylindrical. Basidiospores tau txais kev pab raws li lub ntsiab dispersal unit ntawm basidiomycetes fungi.
Basidiospores yog tsim thaum lub sij hawm kev sib deev ntawm basidiomycetes. Ib qho basidium tsim plaub basidiospores sab nraud los ntawm meiosis. Ntau lab ntawm basidia muaj nyob rau hauv ib lub hau ntawm ib tug paub tab basidiocarp. Yog li ntawd, ib tug basidiocarp muaj peev xwm tsim tau billions ntawm basidiospores ib zaug. Qee hom Agaricus tuaj yeem tsim ntau lab tus basidiospores los ntawm ib qho basidiocarp. Puffball fungus Calvatia gigantea tau txheeb xyuas tias yog hom tsiaj uas tsim txog tsib trillion basidiospores.

Summary – Ascospore vs Basidiospore
Ascospore thiab basidiospore yog ob hom kev sib deev spores tsim los ntawm fungi. Ascospores yog tshwj xeeb rau fungi ascomycetes, thiab lawv tau tsim hauv asci. Basidiospores yog tshwj xeeb rau basidiomycetes, thiab lawv yog tsim nyob rau hauv basidia. Ascospores tsim endogenously thaum basidiospores tsim exogenously. Qhov no yog qhov txawv ntawm ascospore thiab basidiospore.
