Nws yog tsim los ntawm dej, ntsev, thiab proteins. Hauv eukaryotic hlwb, cytoplasm suav nrog tag nrho cov khoom hauv lub cell thiab sab nraum lub nucleus. Tag nrho cov organelles nyob rau hauv eukaryotic hlwb, xws li lub nucleus, endoplasmic reticulum, thiab mitochondria, nyob rau hauv lub cytoplasm.
Yuav ua li cas hauv cytoplasm ntawm ib lub cell?
Cytoplasm txhawb nqa thiab tshem tawm cov organelles thiab cellular moleculesthaum ua cov txheej txheem xws li cellular respiration rau ua pa, synthesizing proteins thiab muaj faib cov hlwb los ntawm ob qho tib si mitosis thiab meiosis.
cytoplasm tshwm sim nyob qhov twg hauv cell?
Cytoplasm, cov khoom semifluid ntawm ib lub xovtooj ntawm yog sab nraud rau cov ntaub so ntswg nuclear thiab sab hauv mus rau cellular membrane, qee zaum piav raws li cov ntsiab lus nonnuclear ntawm protoplasm. Hauv eukaryotes (piv txwv li, cov hlwb muaj cov nucleus), cytoplasm muaj tag nrho cov organelles.
Thaum twg cytoplasm nrhiav tau?
Lub cytoplasm yog cov khoom ntawm lub neej, nws ua haujlwm ua kua zaub molecular thiab nws nyob hauv cytoplasm qhov twg tag nrho cov cellular organelles raug tshem tawm thiab raug khi ua ke los ntawm lipid bilayer membrane. Lub cytoplasm tau pom nyob rau hauv lub xyoo 1835los ntawm Robert Brown thiab lwm tus kws tshawb fawb.
Cytoplasm siv rau hauv lub cell yog dab tsi?
Lub cytoplasm ua haujlwm txhawb nqa thiab tshem tawm cov organelles thiab cellular molecules. Ntau cov txheej txheem cellular kujtshwm sim nyob rau hauv lub cytoplasm, xws li protein synthesis, thawj theem ntawm cellular respiration (lub npe hu ua glycolysis), mitosis, thiab meiosis.

Dab tsi yog ib feem ntawm cov kua dej ntawm cytoplasm?
Cytoplasm, cov khoom semifluid ntawm ib lub xovtooj ntawm sab nraud rau cov ntaub so ntswg nuclear thiab sab hauv mus raucellular membrane, qee zaum piav raws li cov ntsiab lus nonnuclear ntawm protoplasm. Hauv eukaryotes (piv txwv li, cov hlwb muaj cov nucleus), cytoplasm muaj tag nrho cov organelles.
Puas pom nyob rau hauv cytoplasm ntawm eukaryotic cell?
Tag nrho cov organelles nyob rau hauv eukaryotic hlwb, xws li lub nucleus, endoplasmic reticulum, thiab mitochondria, nyob rau hauv lub cytoplasm. Dab tsi tuaj yeem pom hauv cytoplasm? Cov organelles hauv cytoplasm tseem ceeb heev rau kev saib xyuas ntawm tes.
Thaum lub sijhawm tsim cov cellular kev faib tawm ntawm cytoplasm hu ua?
Cytokinesis (/ˌsaɪtoʊkɪˈniːsɪs/) yog ib feem ntawm cov txheej txheem ntawm tes faib thaum lub sij hawm cytoplasm ntawm ib leeg eukaryotic cell faib ua ob lub hlwb. Cytoplasmic division pib thaum lub sij hawm los yog tom qab lub sij hawm lig ntawm nuclear faib nyob rau hauv mitosis thiab meiosis.
Ntawm ribosomes hauv cytoplasm?
Ribosomes yog pom 'dawb' hauv cytoplasmlossis khi rau endoplasmic reticulum (ER) los ua ER ntxhib. Nyob rau hauv ib tug mammalian cell yuav muaj li 10 lab ribosomes. Ob peb ribosomes tuaj yeem txuas rau tib lub mRNA strand, cov qauv no hu ua polysome.
Hom rna twg los ntawm nucleoplasm mus rau cytoplasm?
Messenger RNA (mRNA), molecule hauv cov hlwb uas nqa cov lej los ntawm DNA hauv lub nucleus mus rau qhov chaw ntawm cov protein synthesis hauv cytoplasm (cov ribosomes). hom RNA twg tuaj yeem taug kev hauv cytoplasm? Messenger RNA (mRNA) yog ib leeg-stranded RNA molecule uas yog ntxiv rau ib qho ntawm DNA strands ntawm cov noob.
