Qhov sib txawv tseem ceeb ntawm kev faib cell thiab kev faib hluav taws xob yog qhov kev faib tawm ntawm tes yog txheej txheem ntawm kev faib cov niam txiv cell mus rau hauv ob tug ntxhais cell thaum lub nuclear faib yog txheej txheem kom tau txais ob tug ntxhais nuclei los ntawm kev faib cov niam txiv nucleus..
Ob lub xovtooj ntawm tes thiab kev faib tawm nuclear yog ob hom txheej xwm uas tshwm sim thaum lub sijhawm ntawm lub voj voog. Thiab ob qho tib si yog splitting txheej txheem. Hauv cov lus yooj yooj yim, nyob rau hauv ob qho tib si txheej txheem, ob tug ntxhais cell los yog ob lub nuclei pib los ntawm ib lub cell los yog ib lub nucleus. Kev faib tawm ntawm tes yog cov txheej txheem tag nrho, thiab kev faib tawm nuclear yog ib qho ntawm cov kauj ruam tseem ceeb ntawm kev faib cell. Ntawm qhov tod tes, kev faib tawm nuclear yog ua raws li cytokinesis. Kab lus no npaj siab los tham txog qhov sib txawv ntawm kev faib cell thiab kev faib nuclear.
Cell Division yog dab tsi?
Cell division yog txheej txheem kom tau ob tug ntxhais cell los ntawm kev faib ntawm ib leeg niam txiv cell. Raws li kev tshawb xav ntawm tes niaj hnub, cov hlwb tshiab tuaj txog ntawm cov hlwb ua ntej. Yog li ntawd, cell division yog txheej txheem ntawm kev tsim cov hlwb tshiab los ntawm cov uas twb muaj lawm. Nuclear division thiab cytokinesis yog cov kauj ruam tseem ceeb hauv kev faib cell.
Daim duab 01: Cell Division
Ntxiv mus, kev faib cell yog ob hom tseem ceeb xws li mitosis (vegetative cell division) thiab meiosis (cell division for the formation of gametes). Cov noob qoob loo faib los ntawm mitosis, thiab nws yog ib qho tseem ceeb rau kev loj hlob thiab kho thiab tseem rau kev yug me nyuam asexual. Ib yam li ntawd, kev tsim ntawm gametes yog qhov tseem ceeb rau kev sib deev. Gametes yog tsim los ntawm meiotic cell division. Meiosis txhim kho kev hloov pauv ntawm caj ces vim yog kev sib xyaw ntawm txiv neej thiab poj niam gametes, random faib ntawm chromosomes thiab hla ntawm homologous chromosomes.
Nuclear Division yog dab tsi?
Nuclear faib cais niam txiv nucleus ua ob tug ntxhais nuclei. Nws yog thawj kauj ruam hauv kev faib cell. Tom qab ntawd nws ua raws li kev faib cytoplasmic; cytokinesis. Nuclear faib tshwm sim nyob rau hauv mitosis thiab meiosis.
Thaum mitosis, ob tug ntxhais nuclei raug tsim muaj pes tsawg tus chromosomes raws li niam txiv nucleus. Tab sis, meiosis ua rau plaub tus ntxhais nuclei nrog ib nrab ntawm cov chromosomes txog cov chromosomes ntawm niam txiv nucleus.
Daim duab 02: Nuclear Division
Ntxiv mus, prophase, metaphase, anaphase thiab telophase yog plaub kauj ruam tseem ceeb ntawm mitosis. Tab sis thaum lub sij hawm meiosis, ob qhov kev faib tawm nuclear tshwm sim. Lawv yog meiosis I thiab meiosis II thiab tom qab meiosis I, cytokinesis tshwm sim, thiab tom qab ntawd meiosis II tshwm sim ua rau plaub lub hlwb.
Dab tsi zoo sib xws ntawm Cell Division thiab Nuclear Division?
- Cell Division thiab Nuclear Division yog ob qhov kev sib cais uas tshwm sim thaum lub voj voog ntawm tes.
- Tsis tas li, ob kauj ruam yog qhov tseem ceeb rau kev tsim cov hlwb tshiab.
Qhov txawv ntawm Cell Division thiab Nuclear Division yog dab tsi?
Ob lub xovtooj ntawm tes thiab kev faib tawm nuclear yog qhov tseem ceeb txhawm rau ua kom cov hlwb tshiab uas xav tau rau kev loj hlob, kho thiab kev sib deev. Qhov tseeb, kev faib tawm nuclear yog ib feem ntawm kev faib cell. Txawm li cas los xij, muaj qhov sib txawv ntawm cell division thiab nuclear division. Cell division yog txheej txheem ntawm tsim cov cell tshiab ntawm niam txiv cell. Txawm li cas los xij, kev faib tawm nuclear yog kev faib cov khoom siv caj ces ntawm niam txiv nucleus rau hauv tus ntxhais nuclei. Yog li, peb tuaj yeem xav txog qhov no yog qhov sib txawv tseem ceeb ntawm kev faib cell thiab kev faib tawm nuclear. Tsis tas li ntawd, lwm qhov sib txawv ntawm kev faib cell thiab kev faib tawm nuclear yog cov xwm txheej loj uas tshwm sim thaum ob txoj haujlwm no. Cov hauv qab no infographic ntawm qhov sib txawv ntawm cell division thiab nuclear division muab cov ntaub ntawv ntau ntxiv txog qhov sib txawv no.
Summary – Cell Division vs Nuclear Division
Ob lub xovtooj ntawm tes thiab kev faib tawm nuclear yog ob hom txheej xwm uas tshwm sim thaum lub sijhawm ntawm lub voj voog. Qhov sib txawv tseem ceeb ntawm cell division thiab nuclear division yog nyob ntawm cov txheej txheem splitting. Cell division yog txheej txheem ntawm kev faib cov niam txiv cell mus rau hauv cov ntxhais cell thaum lub nuclei faib yog cov txheej txheem ntawm niam txiv nucleus rau hauv tus ntxhais nuclei. Txawm li cas los xij, kev faib tawm nuclear yog ib qho ntawm ob theem ntawm kev faib cell. Ob qho cell division thiab nuclear faib yog qhov tseem ceeb rau kev tsim cov hlwb tshiab thiab gametes. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm cell division thiab nuclear division.
