Prokaryotes ( kab mob ) undergo ib tug vegetative cell faib hu ua binary fission, qhov twg lawv cov khoom siv caj ces raug cais sib npaug rau hauv ob tus ntxhais hlwb . Thaum binary fission tej zaum yuav yog txoj kev ntawm kev faib los ntawm feem ntau prokaryotes, muaj lwm txoj kev ntawm kev faib , xws li budding, uas tau pom.
Ib sab ntawm no, yuav ua li cas cov kab mob cell faib Amitotically?
Feem ntau kab mob hlwb replicate los ntawm binary fission, ib tug txheej txheem uas leej niam cell constricts thiab cais ua ob tus ntxhais zoo tib yam hlwb . Thaum cell division, lub tshuab loj molecular hu ua 'divisome' sib sau ua ke hauv lub cell.
Ib yam li ntawd, qhov kev txiav txim ntawm prokaryotic cell division yog dab tsi? Feem ntau prokaryotic hlwb faib los ntawm cov txheej txheem ntawm binary fission. Hauv eukaryotes, cell faib tshwm sim hauv ob theem loj: mitosis thiab cytokinesis.
Ntxiv mus, 3 hom kev faib cell yog dab tsi?
Cells yuav tsum sib faib thiaj li tsim tau ntau hlwb . Lawv ua tiav qhov no kev faib hauv peb txawv txoj kev hu ua mitosis, meiosis, thiab binary fission. Mitosis yog txheej txheem koj lub cev hlwb siv los tsim cov ntawv luam ntawm lawv tus kheej, hu ua tus ntxhais hlwb.
Tus txheej txheem ntawm kev faib cell hu ua dab tsi?
mitosis / cell faib . Mitosis yog a txheej txheem ntawm nuclear kev faib hauv eukaryotic hlwb uas tshwm sim thaum niam txiv cell faib kom tsim tau ob tug ntxhais zoo tib yam hlwb . Thaum cell faib , mitosis hais tshwj xeeb rau kev sib cais ntawm cov khoom siv caj ces duplicated nqa hauv lub nucleus.
Pom zoo:
Yuav ua li cas cov txheej txheem ntawm cell faib nyob rau hauv eukaryotes feem ntau zoo ib yam li cell faib nyob rau hauv prokaryotes?
Tsis zoo li eukaryotes, prokaryotes (uas suav nrog cov kab mob) tau txais ib hom kev faib cell hu ua binary fission. Hauv qee qhov, cov txheej txheem no zoo ib yam li mitosis; Nws yuav tsum tau rov ua dua ntawm cov cell chromosomes, cais ntawm cov theej DNA, thiab kev sib cais ntawm niam txiv cell cytoplasm
Dab tsi yog cov kab mob piav qhia cov kab mob ntawm tes hauv kev nthuav dav?
Cov kab mob yog cov prokaryotes, tsis muaj cov nuclei zoo thiab cov kab mob sib txuas ua ke, thiab nrog cov chromosomes tsim los ntawm ib lub voj voog DNA kaw. Lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, los ntawm feeb spheres, cylinders thiab kauv threads, rau flagellated rods, thiab filamentous chains
Cov ntaub ntawv dab tsi yog siv los faib cov kab mob mus rau hauv cov thawj thiab lub nceeg vaj?
Cell qauv yog siv los faib cov kab mob mus rau hauv Domains thiab Kingdoms. - Cov qauv ntawm tes siv li cas los faib cov kab mob mus rau hauv pawg taxonomic? Cov kab mob tuaj yeem raug cais thiab muab tso rau hauv Domains los ntawm lawv cov yam ntxwv
Qhov twg ntawm cov hauv qab no yog qib siab tshaj ntawm kev faib tawm rau cov kab mob?
Lub nceeg vaj yog qhov siab tshaj plaws ntawm kev faib tawm thiab muaj ntau hom tsiaj raws li Phylum thaum hom yog qhov tshwj xeeb tshaj plaws uas muaj cov tswv cuab tsawg kawg nkaus
Txoj kev tshawb fawb txog kev faib cov kab mob thoob ntiaj teb yog dab tsi?
Biogeography yog kev kawm txog kev faib cov tsiaj thiab ecosystems hauv thaj chaw thaj chaw thiab los ntawm lub sijhawm geological. Cov kab mob thiab cov zej zog lom neeg feem ntau sib txawv nyob rau hauv ib txwm ua raws li thaj chaw gradients ntawm latitude, elevation, cais thiab thaj chaw nyob
