Mitosis tshwm sim nyob rau hauv tag nrho cov tsiaj eukaryotic hlwb , tshwj tsis yog gametes (phev thiab qe), uas nyob rau hauv meiosis . Hauv mob mitosis , cov cell sib faib
Tsis tas li ntawd, hom cell twg raug meiosis?
Txawm li cas los xij, hauv ntau cov nroj tsuag thiab tsiaj txhu, meiosis yog txwv rau cov kab mob hlwb , qhov twg nws yog qhov tseem ceeb rau kev sib deev. Thaum somatic hlwb undergomitosis mus proliferate, kab mob cov hlwb raug meiosis los tsim haploid gametes (cov phev thiab qe).
Kuj Paub, cov hlwb dab tsi raug mitosis thiab vim li cas? Mitosis yog txoj kev hlwb hauv koj lub cev sib faib thiab tsim tshiab hlwb . Thaum lub sij hawm tus txheej txheem ntawm mob mitosis , cov cell ua ib daim ntawv theej ntawm nws cov DNA thiab mus dhau ntau theem, tag nrho cov uas coj mus rau kev tsim ntawm ob hom hlwb qhov twg muaj ib tug.
Ib yam li ntawd, nws raug nug, hom cell twg tsis raug mitosis?
3 Teb
- Feem ntau, neurons yeej tsis faib los ntawm mitosis.
- Yog; Raws li nrog cov neurons, cov leeg hlwb (myocytes) tsis muaj peev xwm ua rau mob mitosis.
Cov hlwb twg raug meiosis?
Lub cev lub diploid kab kab kab qia hlwb undergomeiosis los tsim haploid gametes (spermatozoa rau txiv neej thiab ova rau poj niam), uas fertilize los tsim zygote. Thediploid zygote nkag mus rov ua dua cellular divisionby mitosis kom loj hlob mus rau hauv lub cev.

Lub teeb hom twg raug thaiv los ntawm peb qhov chaw?
Vim tias peb muaj qhov cua uas thaiv ntau hom hluav taws xob thaum tso rau lwm hom. Hmoov zoo rau lub neej hauv ntiaj teb, peb cov huab cua thaiv tawm qhov teeb meem, muaj zog hluav taws xob zoo li X-rays, gamma rays thiab feem ntau ntawm cov hluav taws xob ultraviolet
Nyob rau hauv hom cell prokaryotes los yog eukaryotes puas cell voj voog tshwm sim Vim li cas?
Cell Cycle and Mitosis (hloov 2015) LUB CELL CYCLE Lub voj voog ntawm tes, lossis lub voj voog ntawm tes faib, yog cov xwm txheej uas tshwm sim hauv lub cell eukaryotic ntawm nws qhov tsim thiab lub sijhawm nws rov ua dua nws tus kheej
Cov hlwb twg hauv lub cev raug mitosis?
Txhua lub cell somatic nyob rau hauv ib tug kab mob nyob rau hauv lub cev undergoes mitosis, qhov no muaj xws li daim tawv nqaij hlwb, qe ntshav, pob txha hlwb, lub cev nqaij daim tawv, cov txheej txheem ntawm cov nroj tsuag thiab fungi, thiab lwm yam. Txawm li cas los xij, thaum kev sib deev hlwb (sperm, qe, spores) undergo meiosis
Hom cell twg muaj ribosomes thiab cell membranes?
Eukaryotes kuj tseem tuaj yeem ua ib leeg xwb. Ob leeg prokaryotic thiab eukaryotic hlwb muaj cov qauv sib xws. Tag nrho cov cell muaj plasma membrane, ribosomes, cytoplasm, thiab DNA. Lub plasma membrane, lossis cell membrane, yog txheej phospholipid uas nyob ib puag ncig ntawm tes thiab tiv thaiv nws los ntawm ib puag ncig sab nraud
Dab tsi yog hom cell uas raug meiosis?
Whereas somatic hlwb raug mitosis rau proliferate, cov kab mob hlwb undergo meiosis los tsim haploid gametes (cov phev thiab qe)
