Prokaryotes ( kab mob ) undergo ib tug vegetative cell faib hu ua binary fission, qhov twg lawv cov khoom siv caj ces raug cais sib npaug rau hauv ob tus ntxhais hlwb . Thaum binary fission tej zaum yuav yog txoj kev ntawm kev faib los ntawm feem ntau prokaryotes, muaj lwm txoj kev ntawm kev faib , xws li budding, uas tau pom.

Ib sab ntawm no, yuav ua li cas cov kab mob cell faib Amitotically?

Feem ntau kab mob hlwb replicate los ntawm binary fission, ib tug txheej txheem uas leej niam cell constricts thiab cais ua ob tus ntxhais zoo tib yam hlwb . Thaum cell division, lub tshuab loj molecular hu ua 'divisome' sib sau ua ke hauv lub cell.

Ib yam li ntawd, qhov kev txiav txim ntawm prokaryotic cell division yog dab tsi? Feem ntau prokaryotic hlwb faib los ntawm cov txheej txheem ntawm binary fission. Hauv eukaryotes, cell faib tshwm sim hauv ob theem loj: mitosis thiab cytokinesis.

Ntxiv mus, 3 hom kev faib cell yog dab tsi?

Cells yuav tsum sib faib thiaj li tsim tau ntau hlwb . Lawv ua tiav qhov no kev faib hauv peb txawv txoj kev hu ua mitosis, meiosis, thiab binary fission. Mitosis yog txheej txheem koj lub cev hlwb siv los tsim cov ntawv luam ntawm lawv tus kheej, hu ua tus ntxhais hlwb.

Tus txheej txheem ntawm kev faib cell hu ua dab tsi?

mitosis / cell faib . Mitosis yog a txheej txheem ntawm nuclear kev faib hauv eukaryotic hlwb uas tshwm sim thaum niam txiv cell faib kom tsim tau ob tug ntxhais zoo tib yam hlwb . Thaum cell faib , mitosis hais tshwj xeeb rau kev sib cais ntawm cov khoom siv caj ces duplicated nqa hauv lub nucleus.
