Dab tsi Ua Dos Roots Zoo tagnrho rau Kawm Mitosis ? Dos hauv paus yog zoo tagnrho rau kawm mitosis vim cov dos muaj cov chromosomes loj dua li cov nroj tsuag feem ntau, ua rau kev soj ntsuam cov hlwb yooj yim dua. Cov hauv paus hniav ntawm cov nroj tsuag kuj tseem loj hlob ntxiv thaum lawv tseem nrhiav dej thiab cov as-ham.

Hauv qhov no, vim li cas Allium Cepa siv rau hauv kev kawm mitosis?

Cov nroj tsuag feem ntau muaj cov chromosomes loj thiab cov chromosome tsawg. Lub hauv paus meristem muaj qhov feem ntau ntawm cov hlwb hauv mob mitosis (1-3). Kev loj hlob hauv paus ntsiab lus ntawm dos, Allium pab muab ib qho yooj yim muaj peev xwm ntawm cov ntaub ntawv rau kawm kev puas tsuaj ntawm cov tshuaj ntawm chromosomes.

Tsis tas li ntawd, vim li cas Whitefish Blastula yog cov qauv zoo rau kev kawm mitosis? Ob cov qauv feem ntau siv los ntawm biologists rau kawm mitosis : cov blastula ntawm a ntses dawb thiab lub hauv paus ntsis ntawm ib tug dos. Cov ntses dawb embryo yog a zoo qhov chaw saib mob mitosis vim tias cov hlwb no tau tawg sai heev thaum cov ntses embryo loj tuaj.

Kev sib raug zoo, lub hom phiaj ntawm kev siv HCL hauv kev sim mitosis yog dab tsi?

4 - Lub hom phiaj ntawm hydrochloric acid yog txhawm rau rhuav tshem cov tshuaj uas sib sau ua ke ntawm cov hlwb (feem ntau pectin), tab sis nws tsis rhuav tshem cov phab ntsa ntawm tes. Cov hydrochloric acid kuj muaj peev xwm tua cov hlwb thiab nres cov txheej txheem ntawm mitosis.

Vim li cas cov nroj tsuag hauv paus lus qhia yog qhov zoo ntawm cov hlwb los tshuaj xyuas mitosis?

Cov cog tip cells siv vim cov hauv paus cheeb tsam yog qhov chaw ceev ceev mob mitosis , qhov twg hlwb yog nquag faib. Tus tsiaj hlwb pom qhov txo qis ntawm prophase mus rau metaphase, tab sis lub sijhawm tsis txo qis hauv anaphase thiab telophase (cov ntaub ntawv yuav luag tas li).
