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.
Pom zoo:
Cov hlwb twg tsis muaj nucleus thiab tsis muaj chromosomes?
Ib lub cell uas tsis muaj nucleus yog ib lub cell prokaryotic. Nws tsuas muaj cov khoom siv caj ces (DNA) hauv nws tab sis tsis muaj daim nyias nyias nyias nyias
Hom cell twg muaj nyob hauv koj lub plhu?
Tib neeg Cheek Epithelial Cells. Cov ntaub so ntswg uas kab hauv lub qhov ncauj yog hu ua basal mucosa thiab yog tsim los ntawm squamous epithelial hlwb. Cov qauv no, feem ntau xav tias yog lub puab tsaig sab plhu, faib kwv yees li ntawm 24 teev txhua txhua 24 teev thiab tau los ntawm lub cev tas li
Hom cell twg muaj cov membrane khi nucleus?
Ib lub cell eukaryotic yog ib lub xovtooj ntawm tes uas muaj cov membrane-bound nucleus thiab lwm cov membrane-bound compartments lossis hnab, hu ua organelles, uas muaj cov haujlwm tshwj xeeb. Lo lus eukaryotic txhais tau hais tias "muaj tseeb kernel" lossis "tseeb nucleus," hais txog qhov muaj cov membrane-bound nucleus hauv cov hlwb
Cov niam txiv muaj ntshav hom A thiab B puas tuaj yeem muaj menyuam nrog O?
Yog lawm, vim txhua tus neeg muaj ob 'genes' rau hom ntshav. Yog li ntawd, ob tug niam txiv uas muaj hom ntshav A lossis B, yog li ntawd, tuaj yeem tsim tau tus menyuam muaj ntshav hom O. Yog tias lawv ob leeg muaj AO lossis BO noob, txhua tus niam txiv tuaj yeem pub cov noob O rau cov xeeb ntxwv. Tom qab ntawd cov xeeb ntxwv yuav muaj OO noob, ua rau lawv cov ntshav hom O
Cov fungi puas muaj cov cell membranes?
Cov fungi yog eukaryotes thiab muaj lub koom haum cellular complex. Raws li eukaryotes, cov kab mob fungal muaj cov membrane-bound nucleus qhov twg DNA yog qhwv ncig histone proteins. Cov kab mob fungal kuj muaj mitochondria thiab cov txheej txheem nyuaj ntawm cov kab mob hauv lub cev, suav nrog endoplasmic reticulum thiab Golgi apparatus
