Eukaryotes kuj tseem tuaj yeem ua ib leeg xwb. Ob leeg prokaryotic thiab eukaryotic hlwb muaj cov qauv sib xws. Tag nrho hlwb muaj a plasma daim nyias nyias , cov ribosomes , cytoplasm , thiab DNA. Cov plasma daim nyias nyias , los yog cell membrane , yog phospholipid txheej uas nyob ib ncig ntawm lub cell thiab tiv thaiv nws los ntawm ib puag ncig sab nraud.

Ib yam li ntawd, nws yog nug, dab tsi hlwb yog ribosomes pom nyob rau hauv?

Ribosomes yog pom hauv ntau qhov chaw nyob ib ncig ntawm eukaryotic cell . Koj tuaj yeem pom lawv ntab hauv cytosol. Cov ntab cov ribosomes ua cov proteins uas yuav siv tau rau hauv cell . Lwm yam cov ribosomes yog pom ntawm endoplasmic reticulum.

Tom qab ntawd, lo lus nug yog, cov kab mob fungi puas muaj ribosomes? Sib koom nta: Nrog rau lwm cov eukaryotes: Cov kab mob fungal muaj membrane-bound nuclei nrog chromosomes uas muaj DNA nrog cov cheeb tsam noncoding hu ua introns thiab coding cheeb tsam hu ua exons. Fungi muaj membrane-bound cytoplasmic organelles xws li mitochondria, sterol-muaj daim nyias nyias, thiab cov ribosomes ntawm 80S hom.

Tom qab ntawd, tag nrho cov cell puas muaj cell membrane?

Txhua lub hlwb muaj ib sab nrauv plasma daim nyias nyias uas tswj tsis tau tsuas yog dab tsi nkag rau hauv cell Tsis zoo li prokaryotes, eukaryotic ntau npaum li cas hlwb kuj muaj internal daim nyias nyias uas encase lawv organelles thiab tswj kev sib pauv ntawm qhov tseem ceeb cell cov khoom.

Puas yog ribosomes hauv cov nroj tsuag thiab tsiaj txhu?

Ribosomes yog nyob rau hauv cov kua hauv lub cell hu ua cytoplasm los yog txuas rau daim nyias nyias. Lawv tuaj yeem pom hauv ob qho tib si prokaryote (cov kab mob) thiab eukaryote ( tsiaj txhu thiab nroj tsuag ) hlwb . Ribosomes yog ib hom organelle. Lwm cov organelles muaj xws li cov nucleus thiab mitochondria.
