Heterokaryotic hais txog cov hlwb uas muaj ob lossis ntau qhov sib txawv ntawm cov nuclei sib koom ib qho cytoplasm. Nws yog lub ntsiab lus ntawm homokaryotic. Qhov no yog qhov theem Tom qab Plasmogamy, fusion ntawm cytoplasm, thiab ua ntej Karyogamy, fusion ntawm nuclei. Nws tsis yog 1n lossis 2n.
Kuj paub yog, dab tsi yog Dikaryotic theem fungi?
Nyob rau hauv lub neej voj voog ntawm kev sib deev kev sib deev kab mob , ib theem haploid hloov nrog lub diploid theem. Hauv cov no fungi , plasmogamy (kev sib xyaw ntawm cov ntsiab lus ntawm tes ntawm ob lub hyphae tab sis tsis yog ntawm ob lub haploid nuclei) ua rau dikaryotic hyphae nyob rau hauv txhua lub cell muaj ob haploid nuclei, ib tug los ntawm txhua tus niam txiv.
Hom kab mob dab tsi ua rau cov fungi muaj? Feem ntau fungi thiab qee cov protists (unicellular eukaryotes) muaj ib tug haploid-dominant lub neej voj voog , nyob rau hauv uas lub "lub cev" ntawm lub cev - uas yog, tus paub tab, ecologically tseem ceeb daim ntawv - yog haploid. Ib qho piv txwv ntawm a kab mob nrog lub haploid-dominant lub neej voj voog yog cov qhob cij dub pwm, uas nws kev sib deev lub neej voj voog muaj nyob rau hauv daim duab hauv qab no.
Ib sab saum toj no, Heterokaryosis nyob rau hauv fungi yog dab tsi?
heterokaryosis Lub xub ntiag nyob rau hauv tib lub cell ntawm ob los yog ntau tshaj genetic sib txawv nuclei. Heterokaryosis tshwm sim nyob rau hauv tej yam fungi , nyob rau hauv uas nws tshwm sim los ntawm fusion ntawm cytoplasm ntawm cov hlwb los ntawm ntau hom yam tsis muaj fusion ntawm lawv cov nuclei.
Dab tsi yog qhov txawv txav uas tsuas muaj fungi?
Fungi muaj ib lub voj voog lub neej tshwj xeeb uas suav nrog txawv txawv 'dikaryotic' lossis 'heterokaryotic' cell hom ntawd muaj ob nuclei. Lub neej voj voog pib thaum lub haploid spore germinates, faib mitotically tsim ib tug 'multicellular' haploid kab mob (hypha).

Nyob rau theem twg DNA nyuaj tshaj plaws kom pom nyob rau hauv lub tshuab tsom iav?
DNA yog qhov nyuaj tshaj plaws kom pom ntawm prophase theem ntawm mitosis. Kev piav qhia: Nyob rau theem prophase, tsis muaj cov chromosomes txhais tau zoo. DNA yog tam sim no nyob rau hauv daim ntawv ntawm nyias chromatin fibers uas nyuaj rau pom nyob rau hauv lub microscope
Nyob rau theem twg DNA nyuaj tshaj plaws pom nyob rau hauv lub tshuab tsom iav?
DNA yog qhov nyuaj tshaj plaws kom pom ntawm prophase theem ntawm mitosis. Kev piav qhia: Nyob rau theem prophase, tsis muaj cov chromosomes txhais tau zoo. DNA yog tam sim no nyob rau hauv daim ntawv ntawm nyias chromatin fibers uas nyuaj rau pom nyob rau hauv lub microscope
Nyob rau theem twg S yog cov molecules tuav nyob rau hauv ib daim ntawv teev?
khov kho Ntawm no, nyob rau theem S twg yog cov molecules tuav nyob rau hauv cov duab meej? Khoom Ib yam li ntawd, qhov kub thiab txias cuam tshuam li cas rau theem hloov? Cov cua sov yog siv los rhuav tshem cov kev sib txuas ntawm cov dej khov molecules thaum lawv tig mus ua kua theem .
Dab tsi yog cov ions nyob rau hauv siab tshaj plaws concentration nyob rau hauv lub extracellular kua?
Cov tshuaj no nyob rau hauv cov kua dej extracellular thiab intracellular. Nyob rau hauv cov kua dej extracellular, cov cation loj yog sodium thiab cov anion loj yog chloride. Qhov loj cation nyob rau hauv cov kua dej intracellular yog poov tshuaj. Cov electrolytes no ua lub luag haujlwm tseem ceeb hauv kev tswj hwm homeostasis
Nyob rau hauv dab tsi organelle yog pyruvate oxidation nqa tawm nyob rau hauv ib lub cell?
Pyruvate oxidation cov kauj ruam Pyruvate yog tsim los ntawm glycolysis nyob rau hauv lub cytoplasm, tab sis pyruvate oxidation tshwm sim nyob rau hauv lub mitochondrial matrix (hauv eukaryotes). Yog li, ua ntej cov tshuaj tiv thaiv tuaj yeem pib, pyruvate yuav tsum nkag mus rau mitochondrion, hla nws daim nyias nyias thiab tuaj txog ntawm matrix
