Prokaryotic hlwb ua tsis yog muaj ib nucle. Ob leeg prokaryotic thiab eukaryotic hlwb muaj cov qauv hauv feem ntau . Txhua lub hlwb 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.
Ntawm no, 4 qhov zoo sib xws ntawm cov hlwb prokaryotic thiab eukaryotic yog dab tsi?
Zoo li ib prokaryotic cell , a eukaryotic cell muaj plasma membrane, cytoplasm, thiab ribosomes, tab sis a eukaryotic cell feem ntau yog loj dua ib prokaryotic cell , muaj ib qho tseeb nucleus (txhais tau tias nws cov DNA yog nyob ib puag ncig los ntawm daim nyias nyias), thiab muaj lwm cov kab mob ua ke uas tso cai rau rau compartmentalization ntawm functions.
Qhov thib ob, prokaryotes thiab eukaryotes muaj dab tsi hauv cov lus teb com? Nkawd ob leeg muaj ribosomes, yog kaw los ntawm plasma membrane, muaj DNA thiab lawv ob leeg muaj cytoplasm. lawv ob leeg muaj cell phab ntsa.
Ntxiv rau qhov no, cov hlwb eukaryotic muaj dab tsi?
Eukaryotic hlwb muaj ntau haiv neeg nyob rau hauv cov duab, daim ntawv thiab muaj nuj nqi. Qee qhov tshwj xeeb sab hauv thiab sab nraud, txawm li cas los xij, yog feem ntau rau txhua tus. Cov no suav nrog plasma ( cell ) membrane, ib tug nucleus, mitochondria, internal membrane khi organelles thiab ib cytoskeleton.
Dab tsi yog 5 qhov zoo sib xws ntawm cov hlwb prokaryotic thiab eukaryotic?
Eukaryotic hlwb muaj cov organelles membrane-bound, nrog rau cov nucleus. Eukaryotes tuaj yeem ua ib leeg lossis ntau lub cell, xws li koj, kuv, nroj tsuag, fungi, thiab kab. Cov kab mob yog ib qho piv txwv ntawm prokaryotes . Prokaryotic hlwb tsis muaj cov nucleus los yog lwm yam membrane-bound organelle.

Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm qhov nrawm thiab nrawm?
Kev sib piv daim duab piv rau Kev Sib Piv Ceev Ceev Tus Nqi Hloov ntawm qhov kev ncua deb Hloov pauv hloov thaum lub cev rov qab mus rau nws qhov chaw pib Yuav tsis xoom Yuav yog xoom Tsiv khoom Ceev ntawm cov khoom txav tsis tuaj yeem tsis zoo. Kev nrawm ntawm cov khoom txav tuaj yeem yog qhov zoo, tsis zoo lossis xoom
Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm kinetic thiab lub zog muaj peev xwm?
Lub Zog Muaj Peev Xwm yog lub zog khaws cia hauv ib qho khoom lossis qhov system vim nws txoj haujlwm lossis kev teeb tsa. Kinetic zog ntawm ib yam khoom yog txheeb ze rau lwm yam khoom txav thiab nyob ruaj ruaj hauv nws qhov chaw tam sim ntawd
Puas yog ob txoj kab sib luag zoo sib xws lossis tsis sib xws?
Yog tias ob qhov sib npaug piav txog kab sib luag, thiab yog li cov kab uas tsis sib tshuam, qhov system yog ywj siab thiab tsis sib haum. Yog hais tias ob qhov sib npaug piav txog tib kab, thiab yog li cov kab uas hla tus lej tsis kawg, lub kaw lus yog nyob ntawm thiab sib xws
Dab tsi yog cov khoom siv caj ces hauv prokaryotes thiab eukaryotes?
Feem ntau ntawm cov khoom siv caj ces raug teeb tsa rau hauv chromosomes uas muaj cov DNA uas tswj hwm cov haujlwm ntawm tes. Prokaryotes feem ntau yog haploid, feem ntau muaj ib lub voj voog chromosome pom hauv nucleoid. Eukaryotes yog diploid; DNA tau teeb tsa rau hauv ntau cov kab chromosomes pom hauv cov nucleus
Dab tsi yog qhov sib txawv ntawm kev sib tw thiab cov lej sib xws?
Peb siv cov lej sib xws los ua kom qhov teeb meem yooj yim dua los daws hauv peb lub taub hau los ntawm kev hloov txhua tus lej mus rau qhov ze tshaj kaum, nees nkaum, tsib caug lossis puas. Tab sis yog tias peb ua cov lej sib xws thiab sib npaug mus rau qhov ze tshaj plaws puas lossis kaum qhov chaw, 300 thiab 350 yog qhov yooj yim dua los suav hauv peb lub taub hau
