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 yog lub cytoplasm yog Semifluid matrix?
Lub semi kua matrix lossis lub cytoplasm yog cov ntsiab lus sab hauv ntawm lub xovtooj, sib cais los ntawm cov nucleus uas yog nyob rau hauv lub cell membrane. Tag nrho cov cell organelles raug tshem tawm hauv cytoplasm. Lub semi fluid matrix tam sim no nyob rau hauv lub nucleus yog hu ua nucleoplasm uas muaj chromosomes.
Dab tsi yog qhov sab hauv ntawm cytoplasm ntawm ib lub cell?
Cytosol. Lub cytosol yog ib feem ntawm lub cytoplasm tsis muaj nyob rau hauv daim nyias nyias organelles. Cytosol tsim txog li 70% ntawm lub cell ntim thiab yog ib qho kev sib xyaw ntawm cytoskeleton filaments, yaj molecules, thiab dej.
Dab tsi yog qhov loj ntawm cytoplasm?
Cytoplasm muaj ob lub ntsiab lus: the endoplasm thiab ectoplasm. Lub endoplasm nyob rau hauv nruab nrab cheeb tsam ntawm lub cytoplasm, thiab nws muaj organelles. Lub ectoplasm yog cov khoom zoo li gel nyob rau sab nraud ntawm cytoplasm ntawm ib lub xovtooj.
Dab tsi yog ntab hauv lub cytoplasm?
Ribosomes muaj nyob hauv ntau qhov chaw nyob ib puag ncig eukaryotic cell. Tej zaum koj yuav pomLawv ntab hauv cytosol. Cov ribosomes ntab ua cov proteins uas yuav siv rau hauv lub cell. Lwm cov ribosomes pom nyob rau ntawm endoplasmic reticulum.
