Thaum cov qe ntshav liab nyob hauv a hypertonic (siab dua) daws, dej ntws tawm ntawm lub xovtooj sai dua li nws tuaj. ntshav.
hom cell li cas crenation tshwm sim nyob rau hauv?
Crenation Versus Plasmolysis
Thaum crenation tshwm sim hauv tsiaj hlwb, cov hlwb uas muaj phab ntsa ntawm tes tsis tuaj yeem ntsws thiab hloov cov duab thaum muab tso rau hauv cov tshuaj hypertonic. Nroj tsuag thiab kab mob hlwb hloov mus rau plasmolysis.
Puas hypertonic ua rau crenation?
Crenation yog ib qho tshwm sim uas tshwm sim thaum cells ntawm cov tsiaj keeb kwm raug nthuav tawm rau cov tshuaj hypertonic, txhais tau hais tias cov tshuaj uas da dej rau lub hlwb muaj cov ntsiab lus siab ntawm solutes.
txheej txheem crenation yog dab tsi?
Crenation lub ntsiab lus
A txheej txheem tshwm sim los ntawm osmosis uas cov qe ntshav liab, nyob rau hauv cov tshuaj hypertonic, undergo shrinkage thiab tau txais ib tug notched los yog scalloped nto.
Dab tsi yog tshuaj hypotonic rau cov qe ntshav liab?
Piv txwv li, an iso-osmolar urea tov yog hypotonic rau cov qe ntshav liab, ua rau lawv cov lysis. Qhov no yog vim urea nkag mus rau hauv lub cell cia nws cov concentration gradient, ua raws li dej.
