Yog tias concentration ntawm qabzib nyob rau hauv dej sab nraud ntawm lub cell yog siab tshaj qhov concentration hauv , dej yuav nyiam tawm ntawm ntawm tes los ntawm osmosis. c. qabzib yuav nyiam nkag rau hauv ntawm tes los ntawm osmosis.

Ib yam li ib tug yuav nug, yuav ua li cas tshwm sim yog tias qhov concentration ntawm cov dej sab hauv thiab sab nraud ntawm tes yog tib yam?

Hauv kev daws teeb meem isotonic, ntws ntawm dej hauv thiab tawm ntawm lub cell yog tshwm sim ntawm tib yam tus nqi. Dej txav mus rau hauv thiab tawm ntawm tes los ntawm osmosis. Yog ib ntawm tes yog nyob rau hauv cov tshuaj hypertonic, cov tshuaj muaj qis dua dej concentration tshaj li ntawm tes cytosol, thiab dej txav tawm ntawm lub cell kom txog thaum ob qho kev daws teeb meem yog isotonic.

Tsis tas li ntawd, yuav ua li cas yaj cov ntaub ntawv yuav txav los ntawm sab nraud mus rau sab hauv ntawm lub xovtooj ntawm tes thaum lub hauv paus concentration ntawm cov khoom yog siab tshaj qhov sab nraud concentration? Ib qho tshuaj hypertonic yog qhov twg sab nraum tus ntawm tes , cov yaj tshuaj yog ntau concentrated tshaj sab hauv tus ntawm tes . Yog li ntawd, muaj ntau dej sab nraum tus cell tshaj sab hauv . Cells Hauv kev daws teeb meem hypotonic kev paub osmosis. Dej txav nkag mus rau hauv lub plasma membrane ntawm tes.

Hais txog qhov no, thaum lub concentration ntawm cov kuab tshuaj ntau dua sab nraum lub cell tshaj sab hauv?

Ib qho kev daws teeb meem hypotonic yog ib qho uas concentration ntawm solutes yog ntau dua nyob rau hauv tus cell tshaj sab nraud ntawm nws, thiab cov tshuaj hypertonic yog ib qho qhov twg cov concentration ntawm solutes ntau dua sab nraum lub cell tshaj sab hauv nws.

Vim li cas dej txav ntawm qhov qis mus rau qhov siab?

Lub diffusion ntawm tej kua, roj molecules los ntawm qis concentration rau siab concentration ntawm cov kuab tshuaj uas yog yooj yim los ntawm lub xub ntiag ntawm lub semi-permeable membrane yog hu ua 'Osmosis'. Dej molecules txav los ntawm qis osmotic siab rau qhov siab dua osmotic siab cheeb tsam.
