Lub nucleus ntawm eukaryotic hlwb yog tsim los ntawm cov protein thiab deoxyribonucleic acid, lossis DNA. Lub DNA yog nruj nreem qhwv ib ncig ntawm cov protein tshwj xeeb hu ua histones; qhov sib xyaw ntawm DNA thiab histone proteins hu ua chromatin . Txawm tias prokaryotic hlwb tsis muaj nucleus, lawv muaj DNA.
Ib yam li ntawd, tib neeg nug, puas muaj chromatin nyob rau hauv prokaryotic lossis eukaryotic hlwb?
Chromosomes thiab Chromatin . Tsis tsuas yog cov genomes ntawm feem ntau eukaryotes complex ntau dua li cov prokaryotes tab sis DNA ntawm eukaryotic hlwb kuj raug teeb tsa txawv ntawm qhov prokaryotic hlwb . Cov genomes ntawm prokaryotes yog muaj nyob rau hauv ib chromosomes, uas feem ntau yog ncig DNA molecules.
Ib yam li ntawd, dab tsi muaj nyob hauv cov hlwb prokaryotic tab sis tsis yog eukaryotic? Prokaryotic Cell . Eukaryotic hlwb muaj cov membrane-bound organelles, xws li cov nucleus, thaum prokaryotic hlwb ua tsis yog . Qhov txawv hauv cellular qauv ntawm prokaryotes thiab eukaryotes suav nrog muaj mitochondria thiab chloroplasts, cov cell phab ntsa, thiab tus qauv ntawm chromosomal DNA.
Ib yam li ntawd, cov cell yog chromatin hauv dab tsi?
Chromatin yog ib pawg ntawm cov khoom siv caj ces muaj xws li DNA thiab cov proteins uas sib xyaw ua ke chromosomes Thaum lub sij hawm eukaryotic cell faib. Chromatin nyob rau hauv lub nucleus ntawm peb lub hlwb.
Cov qauv dab tsi tsuas pom muaj nyob hauv cov hlwb prokaryotic?
Cov ntsiab lus
- Tag nrho cov cell muaj plasma membrane, ribosomes, cytoplasm, thiab DNA.
- Cov hlwb prokaryotic tsis muaj cov nucleus thiab cov txheej txheem sib khi.
- Eukaryotic hlwb muaj cov nucleus thiab cov txheej txheem ua ke hu ua organelles.

Puas yog cov hlwb hauv koj lub cev prokaryotic lossis eukaryotic?
Tib neeg nrog rau tsiaj tsiaj thiab nroj tsuag yog tsim los ntawm eukaryotic hlwb. Cov kab mob uas tsim nrog cov hlwb prokaryotic yog cov kab mob thiab archaea. Txawm li cas los xij txhua lub hlwb muaj cov yam ntxwv zoo sib xws. Piv txwv li, eukaryotes thiab prokaryotes ob leeg muaj plasma daim nyias nyias, qhov no tiv thaiv cov ntaub ntawv extracellular nkag mus rau hauv lub cell
Puas yog ib qho nucleus pom hauv cov hlwb prokaryotic?
Prokaryotes yog cov kab mob unicellular uas tsis muaj organelles los yog lwm yam hauv cov txheej txheem hauv cov ntaub so ntswg. Yog li ntawd, lawv tsis muaj ib tug nucleus, tab sis, feem ntau, feem ntau muaj ib tug chromosome: ib daim voj voog, ob-stranded DNA nyob rau hauv ib cheeb tsam ntawm lub cell hu ua nucleoid
Dab tsi yog pom hauv eukaryotic hlwb tab sis tsis yog cov hlwb prokaryotic?
Eukaryotic hlwb muaj cov kab mob sib txuas ua ke, xws li cov nucleus, thaum cov hlwb prokaryotic tsis ua. Qhov sib txawv hauv cellular qauv ntawm prokaryotes thiab eukaryotes muaj xws li muaj mitochondria thiab chloroplasts, phab ntsa cell, thiab cov qauv ntawm chromosomal DNA
Dab tsi tsuas pom muaj nyob hauv cov hlwb prokaryotic?
Ib tug raug prokaryotic cell muaj cov cell membrane, chromosomal DNA uas yog concentrated nyob rau hauv ib tug nucleoid, ribosomes, thiab ib tug cell phab ntsa. Qee cov hlwb prokaryotic kuj tseem muaj flagella, pili, fimbriae, thiab tshuaj ntsiav
Dab tsi yog qhov txawv ntawm cov hlwb prokaryotic thiab prokaryotic?
Prokaryotes yog cov kab mob uas tsim los ntawm cov hlwb uas tsis muaj cell nucleus los yog ib qho membrane-encased organelles. Eukaryotes yog cov kab mob uas tsim los ntawm cov hlwb uas muaj cov membrane-bound nucleus uas tuav cov khoom siv noob caj noob ces nrog rau cov kab mob membrane-bound organelles
