Spores feem ntau haploid thiab unicellular thiab yog tsim tawm los ntawm meiosis nyob rau hauv lub sporangium ntawm ib tug diploid sporophyte. Nyob rau hauv tej yam kev mob zoo lub spore tuaj yeem txhim kho mus rau hauv cov kab mob tshiab uas siv mitotic division, tsim cov multicellular gametophyte, uas nws thiaj li mus rau tsim gametes.
Ntawm no, qhov twg spores tsim?
Hauv khob fungi, lub spore - tsim tawm asci nyob rau sab hauv ntawm lub cev fruiting paub tab. Spores raug tso tawm hauv huab thaum lub asci tawg qhib. Gilled nceb muaj basidia nyob rau ntawm gills nyob rau hauv qab ntawm lub hau. Cov spores tau poob los ntawm gills thaum paub tab.
Kuj Paub, yuav ua li cas spores tsim nyob rau hauv fungi? Fungi reproduce asexually los ntawm fragmentation, budding, los yog tsim spores . Fragments ntawm hyphae tuaj yeem loj hlob tuaj tshiab. Feem ntau hom ntawm asexual reproduction yog los ntawm cov tsim ntawm asexual spores , uas yog tsim los ntawm ib tug niam txiv nkaus xwb (los ntawm mitosis) thiab yog genetically zoo tib yam rau leej niam leej txiv.
Ib yam li ntawd ib tug yuav nug, yog vim li cas spores tsim?
Spores yog cov qauv tsim ntawm 'cov nroj tsuag qis,' cov nroj tsuag uas tsis paj. Fungi, algae, thiab txawm qee cov kab mob tag nrho daim ntawv spores thaum lawv xav hla lawv cov noob rau. Xav txog lawv zoo li cov noob; lawv tau tsim kom loj hlob ib tsob ntoo tshiab thiab txhua yam lawv xav tau yog qhov chaw tsim nyog kom vam meej.
Dab tsi yog qhov tsim ntawm spore?
Spore tsim yog ib daim ntawv ntawm asexual reproduction. Spore tsim yog txoj hauv kev los tsim cov tib neeg tshiab los ntawm kev tsim cov qauv kev ua me nyuam hu ua spores . *A spore yog ib tug me me spherical los yog oval qauv uas tiv thaiv tus neeg yav tom ntej nyob rau hauv ib tug tuab tiv thaiv npog.

Dab tsi yog qhov kev sib raug zoo ntawm tag nrho cov khoom tsim tau thiab cov khoom tsim tawm thawj zaug sau qhov sib npaug?
Koj tuaj yeem pom tias koj tus lej nyiaj hauv tuam txhab nyiaj tau txiav txim siab raws li hauv qab no: Koj qhov Net ntau lawm yog sib npaug rau koj qhov Kev Tsim Nyog Tag Nrho Tshem Tawm Tawm, uas yog tib yam li qhov sib npaug saum toj no uas hais txog Net Primary Production (NPP) = Gross Primary Production (GPP) Kev ua pa tawm (R)
Yuav ua li cas cog spores thiab kab mob spores txawv?
Ib qho yooj yim txhais ntawm ib tug spore yog hais tias nws yog ib tug dormant ciaj sia taus cell. Tag nrho cov fungi tsim spores; Txawm li cas los xij, tsis yog txhua tus kab mob tsim spores! Tsis tas li ntawd, cov kab mob fungal thiab kab mob spores txawv ntawm qhov lawv ua haujlwm thiab lawv tsim li cas
Qhov twg ntawm 5s txheej txheem xav kom koj cais cov khoom tsim nyog thiab tsis tsim nyog ntawm qhov chaw ua haujlwm?
Sort (seiri) - Qhov txawv ntawm qhov tsim nyog thiab tsis tsim nyog, thiab tshem tawm yam koj tsis xav tau. Ncaj (seiton) - Kev coj ua ntawm kev khaws cia kom cov khoom tsim nyog tuaj yeem khaws tau zoo (tsis muaj pov tseg) raws sijhawm, yooj yim rau txhua tus neeg
Puas yog nceb rov tsim dua los ntawm spores?
Cov fungi, ntawm chav kawm, tsis siv cov noob los yug me nyuam. Lawv yog cov tsis-vascular thiab rov tsim dua los ntawm spores. Tab sis qhov saum toj kawg nkaus hauv av uas peb xav tias yog nceb yog qhov sib npaug ntawm cov qauv txiv hmab txiv ntoo, uas yog tsim los ntawm cov kab hauv av hu ua mycelium
Qhov twg yog qhov kev tsim kho pob qij txha?
Kev tsim kho kev sib koom ua ke yog ib qho ntawm cov pob qij txha hauv qhov chaw tsim kho uas tuaj yeem nyob ntawm phab ntsa thiab slabs. Kev siv nrov tshaj plaws ntawm kev tsim kho kev sib koom ua ke yog ntawm cov slabs tshem tawm. Qhov tseeb, nws txhais tau hais tias yog ib qho kev txiav ntev hauv lub slab thaum lub sij hawm ua vaj tse pouring txheej txheem
