Qhov sib txawv tseem ceeb ntawm mitosis thiab amitosis yog amitosis yog qhov yooj yim tshaj plaws ntawm kev faib cell uas pom los ntawm cov kab mob thiab cov poov xab, thiab lwm yam thaum mitosis yog cov txheej txheem nyuaj ntawm cell division, uas tshwm sim ntawm chromosome replication thiab nuclear division.
Cells faib thiab tsim cov hlwb tshiab, thiab nws yog ib hom txheej txheem ntawm cell proliferation. Muaj peb txoj kev faib tawm ntawm tes sib txawv xws li amitosis, mitosis thiab meiosis. Kev faib tawm ntawm tes sib txawv ntawm cov kab mob, tshwj xeeb tshaj yog cov eukaryotes thiab prokaryotes. Cov kab mob thiab cov poov xab qhia tau yooj yim thiab ncaj qha cell division txheej txheem hu ua binary fission thiab budding. Cov no yog cov txheej txheem amitotic uas yuav ua rau cov menyuam ntxhais. uas tsis zoo ib yam. Ntawm qhov tsis sib xws, mitosis cell faib ua ob lub hlwb zoo tib yam.
Mitosis yog dab tsi?
Mitosis yog theem thib ob loj ntawm lub voj voog ntawm tes. Yog li ntawd, thaum lub sij hawm mitosis, cell nucleus hloov mus ua ob lub nuclei thiab thaum kawg, lub cell faib ua ob lub hlwb. Txawm li cas los xij, mitosis txuas ntxiv rau lub sijhawm luv luv. Muaj plaub subphases ntawm mitosis uas yog prophase, metaphase, anaphase thiab telophase. Thaum lub sij hawm prophase, centrosomes tsiv mus rau hauv ob tug ncej ntawm tes, nuclear membrane pib ploj mus, microtubules pib mus, chromosomes condense ntau thiab khub nrog ib leeg thiab tus muam chromatids pom.
Daim duab 01: Mitosis
Thaum lub sijhawm metaphase, cov chromosomes kab ntawm lub phaj metaphase, thiab microtubules txuas nrog cov centrosomes ntawm cov kab chromosomes. Metaphase yog ua raws li anaphase uas tus muam chromatids faib sib npaug thiab sib cais kom tsiv mus rau ob tus ncej. Muam chromatids raug rub mus rau ob tug ncej los ntawm microtubules. Thaum lub sij hawm telophase, ob daim ntawv nuclei tshiab thiab pib faib cov ntsiab lus ntawm tes ntawm ob sab ntawm tes. Cell cytoplasm faib ua ob lub hlwb tshiab. Cov txheej txheem no hu ua cytokinesis. Tom qab cytokinesis, ob lub hlwb zoo ib yam yuav tsim, thiab cov hlwb tshiab yuav txuas ntxiv mus rau rov ua dua lub voj voog ntawm tes.
Amitosis yog dab tsi?
Amitosis yog ib qho yooj yim ntawm kev faib cell uas tshwm sim los ntawm kev faib cell ncaj qha. Nws tshwm sim feem ntau hauv prokaryotes uas tsis muaj cov kab mob sib txuas thiab cov nucleus. Yog li, amitosis txawv ntawm mitosis, uas yog kev faib cell ntawm eukaryotes los ntawm ntau yam. Hauv amitosis, tsis muaj qhov pom ntawm chromosomes thiab spindle tsim.
Daim duab 02: Amitosis
Nyob rau hauv qee cov eukaryotes, uas dhau mus amitosis, cov ntaub so ntswg nuclear tseem nyob tsis tau. Tab sis amitosis tsis yog ib qho txheej txheem nyuaj thaum piv rau mitosis uas tshwm sim ntawm ntau theem. Ciliates yog ib hom kab mob uas kis tau amitosis. Tsis tas li ntawd, cov kab mob faib amitotically los ntawm binary fission. Moroever, budding ntawm poov xab kuj yog ib txoj kev amitotic. Hauv qhov no thaum lub sij hawm amitosis, lub nucleus faib ua ob ntu, thiab tom qab ntawd cytoplasm faib ua ob lub hlwb.
Dab tsi zoo sib xws ntawm Mitosis thiab Amitosis?
- Mitosis thiab amitosis yog ob txoj kev faib cell.
- Ob tus ntxhais lub hlwb.
- Nyob rau hauv ob txheej txheem, ib leeg niam txiv cell tsim.
Qhov txawv ntawm Mitosis thiab Amitosis yog dab tsi?
Mitosis yog ib hom kev faib tawm ntawm tes uas ib lub cell eukaryotic cais cov chromosomes rau hauv ob qho tib si thiab tsim ob tus ntxhais nuclei thiab tom qab ntawd ob tus ntxhais cell uas zoo ib yam rau niam txiv cell thaum amitosis yog ib qho yooj yim cell faib txheej txheem nyob rau hauv uas Ib qho yooj yim cleavage ntawm lub nucleus tshwm sim thiab tsim cov ntxhais hlwb, tsis muaj spindle tsim los yog cov tsos ntawm chromosomes.
Cov duab hauv qab no nthuav tawm cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm mitosis thiab amitosis hauv daim ntawv teev npe.
Summary – Mitosis vs Amitosis
Amitosis thiab mitosis yog ob hom kev faib cell. Amitosis yog ib qho txheej txheem yooj yim uas suav nrog kev faib cov nucleus rau hauv ob feem thiab faib cov cytoplasm. Mitosis yog txheej txheem nyuaj uas tshwm sim los ntawm chromosome replication thiab nuclear division. Mitosis yields ob genetically zoo tib yam ntxhais cell tab sis, amitosis tsis ua rau cov noob caj noob ces zoo tib yam li tus ntxhais vim kev faib ntawm niam txiv alleles tshwm sim random. Cov kab mob, cov poov xab thiab ciliates qhia amitosis. Eukaryotes feem ntau raug mitosis. Qhov no yog qhov txawv ntawm mitosis thiab amitosis.
