Hauv eukaryotes, lub cytoplasm tseem suav nrog membrane-bound organelles, uas raug tshem tawm hauv lub cytosol . Lub cytoskeleton, a network ntawm fibers uas txhawb nqa lub cell thiab muab nws cov duab, kuj yog ib feem ntawm cov cytoplasm thiab pab npaj cellularcomponents.
Ua raws li qhov no hauv kev xav, dab tsi yog lub network ntawm cov protein fibers?
A network ntawm cov protein fibers nyob rau hauv cytoplasm ntawm aeukaryotic cell; muaj xws li microfilaments, intermediate filaments, thiab microtubules. Microtubules. Lub thickest ntawm peb mainkins ntawm fibers tsim cov cytoskeleton ntawm eukaryoticcell; ib tug ncaj, hollow raj ua los ntawm globular cov proteins npe tubulins.
Tsis tas li ntawd, cytoplasm ntawm lub cell yog dab tsi? Cytoplasm yog ib tug tuab tov uas puv txhua cell thiab yog enclosed los ntawm cell daim nyias nyias. Nws yog tsim los ntawm dej, ntsev, thiab cov proteins. Tag nrho cov organelles nyob rau hauv eukaryotic hlwb , xws li cov nucleus, endoplasmic reticulum, thiab mitochondria, yog nyob rau hauv lub cytoplasm.
Kuj tseem paub yog, cytoplasm yog dab tsi thiab nws txoj haujlwm?
Nws yog tsim los ntawm feem ntau dej thiab ntsev. Cytoplasm muaj nyob rau hauv tus cell membrane ntawm txhua hom cell thiab muaj tag nrho cov organelles thiab cell seem. Cytoplasm muaj ntau yam muaj nuj nqi hauv tus cell. Nws pab sau tus cell thiab khaws cov organelles hauv lawv qhov chaw.
Puas yog cytoskeleton thiab cytoplasm yog tib yam?
Cov cytoskeleton tus kab mob yog tsim los ntawm cov protein filaments thiab pom thoob plaws hauv lub cell eukaryotic. Cov cytosol yog qhov tseem ceeb ntawm cov cytoplasm , cov kua dej uas sau rau hauv lub cell. Cov cytoplasm yog txhua yam nyob rau hauv lub cell tsuas yog rau lub cytoskeleton tus kab mob andmembrane-bound organelles.

Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
