Prokaryotic cells tsis muaj lub nucleus ncig los ntawm ib qho kev sib txuas ntawm cov ntaub so ntswg nuclear thiab feem ntau muaj ib qho, ncig chromosome nyob rau hauv ib lub nucleoid. Eukaryotic hlwb muaj ib lub nucleus ncig los ntawm ib tug complex nuclear membrane uas muaj ntau yam, chromosomes zoo li tus pas nrig. Tag nrho cov nroj tsuag thiab cov tsiaj hlwb yog eukaryotic.
Pob hlwb prokaryotic puas muaj kev sib cais?
Ib yam li, kev sib cais, feem ntau sau tseg tias yog qhov txawv ntawm cov hlwb eukaryotic, kuj tseem muaj nyob hauv lub ntiaj teb prokaryotic hauv daim ntawv ntawm cov protein-bounded thiab lipid-bounded organelles.
eukaryotic cell compartmentalized li cas?
Nyob hauv eukaryotic hlwb, compartmentalization yog tsim los ntawm kev siv cov txheej txheem ntawm cov ntaub so ntswg sab hauv. Cov membranes nyob ib puag ncig lub nucleus, tsim cov folds ntawm endoplasmic reticulum thiab Golgi complex, thiab ib puag ncig organelles zoo li chloroplasts thiab mitochondria.
Yuav ua li cas prokaryotes compartmentalize cov tshuaj tiv thaiv?
Ib qho ntawm qhov sib txawv loj ntawm eukaryotes thiab prokaryotes yog tias eukaryotes compartmentalize lawv cov txheej txheem sab hauv hauv daim nyias nyias organelles. … Hauv prokaryotes, RNA hloov mus rau cov protein sai tom qab tsim los ntawm DNA, vim lawv tsis muaj cov nucleus lossis endoplasmic reticulum.
Yuav ua li cas prokaryotes compartmentalize tsis muaj organelles?
Feem ntau, cov hlwb prokaryotic tsis tas yuavcompartmentalize vim lawv tsuas muaj ib txoj haujlwm ntawm tes. Yog hais tias ib tug prokaryote yuav tsum tau ua ntau tshaj ib txoj hauj lwm, lawv muaj peev xwm siv lipids thiab proteins los khi organelle zoo li cov qauv hauv lawv cytoplasm.

Vim li cas folded daim nyias nyias yog qhov zoo rau lub cell?
Sib piv thiab sib piv cov haujlwm ntawm phab ntsa ntawm tes rau kev ua haujlwm ntawm plasma membrane. Lub folding nce thaj tsam qhov chaw tshuaj lom neeg tshwm sim. … Muab lub npe hu ua organelle uas muaj daim nyias nyias nyias. Piv txwv li:
Dab tsi yog gelatinous txheej txheej ntawm prokaryotic hlwb?
Prokaryotic cell phab ntsa tuaj yeem tsim los ntawm peptidoglycan (cov kab mob) lossis pseudopeptidoglycan (archaea). Cov kab mob Gram-zoo kab mob yog cov yam ntxwv los ntawm cov txheej peptidoglycan tuab, thaum cov kab mob gram-tsis zoo yog cov yam ntxwv los ntawm ib txheej peptidoglycan nyias ib puag ncig los ntawm txheej membrane.
Puas yog flagellates prokaryotic lossis eukaryotic?
Ib qho piv txwv ntawm eukaryotic flagellate cell yog cov phev cell ntawm mammalian, uas siv nws cov flagellum los txhawb nws tus kheej los ntawm cov poj niam cev xeeb tub. Eukaryotic flagella yog structurally zoo tib yam rau eukaryotic cilia, txawm hais tias kev sib txawv yog qee zaum ua raws li kev ua haujlwm lossis ntev.
Puas yog desmids prokaryotic lossis eukaryotic?
Piv txwv li, zoo li tag nrho eukaryotes, lub desmid cell muaj cov membrane-bound nucleus nrog rau cov organelles, cov phab ntsa ntawm tes uas tsis muaj peptidoglycan (tsis yog txhua tus eukaryotes muaj cell. phab ntsa), linear DNA, thiab cytoskeleton, ntawm lwm yam nta.
Puas yog lub luag haujlwm qhia cov cell yuav coj li cas?
Hidden hauv yuav luag txhua lub cell hauv koj lub cev yog cov tshuaj hu ua DNA. Ib lub noob yog ib ntu luv ntawm DNA. Koj cov noob muaj cov lus qhia uas qhia koj lub hlwb kom ua cov molecules hu ua proteins. Proteins ua ntau yam haujlwm hauv koj lub cev kom koj noj qab nyob zoo.
