Qhov sib txawv tseem ceeb ntawm kev tsim thiab plasmolysis yog qhov crenation yog qhov shrinkage thiab tau txais cov tsos mob ntawm cov qe ntshav liab thaum raug rau cov tshuaj hypertonic thaum plasmolysis yog qhov shrinkage ntawm cov noob hlwb thaum muab tso rau hauv cov tshuaj hypertonic.
Lub cell membrane yog permeable rau dej. Thaum lub cell yog raus rau hauv ib qho kev daws teeb meem uas muaj dej tsawg thiab muaj peev xwm solute siab, lub cell poob nws cov dej los ntawm osmosis. Cov tshuaj suav hais tias yog "kev daws teeb meem hypertonic". Txij li thaum cog cov hlwb txawv ntawm cov tsiaj hlwb vim muaj cov phab ntsa ntawm tes, cov kev hloov pauv txawv thaum lawv muab tso rau hauv cov tshuaj hypertonic. Crenation yog lo lus siv los piav qhia txog cov kev hloov pauv tshwm sim hauv cov qe ntshav liab thaum lawv nkag rau hauv cov tshuaj hypertonic. Nws yog lub xeev ntawm ua shrunken nrog ib tug notched ntug. Plasmolysis yog lub ntsiab lus uas piav qhia txog cov kev hloov pauv tshwm sim hauv cov nroj tsuag thaum lawv nkag rau hauv cov tshuaj hypertonic.
Crenation yog dab tsi?
Crenation yog qhov shrunken notched tsos ntawm cov qe ntshav liab thaum raug rau cov tshuaj hypertonic. Li no, lo lus crenation feem ntau yog siv los piav qhia txog lub xeev ntawm kev poob qis los ntawm cov qe ntshav liab nrog ib qho kev txiav ntug thaum raug rau cov tshuaj ntsev heev. Crenation yog tshwm sim los ntawm osmosis thiab dej poob. Thaum lub xeev isotonic ntawm cov qe ntshav liab raug cuam tshuam, lawv hloov mus rau qhov txawv txav tsis zoo no.

YPlasmolysis yog dab tsi?
Cov dej molecules txav mus thoob qhov kev sib txawv ntawm qhov sib txawv ntawm cov khoom siv semi-permeable los ntawm cov dej ntau dua kom txo cov dej muaj peev xwm. Yog li ntawd, thaum lub cell muab tso rau ntawm ib tug hypertonic tov, dej yuav ntws tawm ntawm lub cell thiaj li yuav tau txais lub ionic concentration ntawm lub sab hauv thiab sab nraud ib puag ncig rau equilibrium. Cov txheej txheem no yog hu ua exosmosis. Kom txog thaum cov dej muaj peev xwm sib npaug, dej yuav txav tawm ntawm tes mus rau qhov kev daws teeb meem. Thaum lub sij hawm tus txheej txheem no, lub protoplasm pib detach los ntawm lub cell phab ntsa. Qhov no yog hu ua plasmolysis. Plasmolysis tshwm sim nyob rau hauv lub siab heev thiab tuaj yeem raug cuam tshuam los ntawm kev kuaj mob los ntawm kev siv cov tshuaj ntsev ntsev ntau ntau.
Daim duab 02: Plasmolysis
Muaj ob hom plasmolysis li concave plasmolysis lossis convex plasmolysis. Concave plasmolysis yog thim rov qab. Thaum lub sij hawm hom plasmolysis no, cov plasma daim nyias nyias tsis tag tshem tawm ntawm phab ntsa ntawm tes; xwb, nws tseem nyob lawm. Convex plasmolysis, ntawm qhov tod tes, yog irreversible thiab yog qib siab ntawm plasmolysis qhov twg cov cell plasma membrane kiag li tshem tawm ntawm phab ntsa ntawm tes. Qhov no tuaj yeem ua rau kev puas tsuaj tag nrho ntawm tes.
Dab tsi zoo sib xws ntawm Crenation thiab Plasmolysis?
- Crenation thiab plasmolysis tshwm sim thaum cov hlwb tau dipped hauv cov tshuaj hypertonic.
- Ob txheej txheem yog los ntawm osmosis.
- Nyob rau hauv ob txoj kev, dej txav ntawm lub xovtooj mus rau sab nraud.
- Cells txo qis hauv ob txheej txheem.
- Nyob rau hauv ob qho tib si, cov dej muaj peev xwm ntawm tes yog siab dua li cov dej muaj peev xwm ntawm cov tshuaj.
Qhov txawv ntawm Crenation thiab Plasmolysis yog dab tsi?
Crenation tshwm sim hauv cov tsiaj hlwb thaum plasmolysis tshwm sim hauv cov nroj tsuag. Crenation yog cov lus teb ntawm cov qe ntshav liab thaum raug cov tshuaj hypertonic, thaum plasmolysis yog cov lus teb ntawm cov nroj tsuag cog thaum raug cov tshuaj hypertonic. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm kev tsim thiab plasmolysis.
Tsis tas li ntawd, hauv kev tsim, cov qe ntshav liab ua kom qis nrog cov npoo npoo thaum nyob rau hauv plasmolysis, cov nroj tsuag cov hlwb yuav shrunken, thiab cov protoplasm shrinks deb ntawm phab ntsa cell.
Summary – Crenation vs Plasmolysis
Crenation yog cov txheej txheem ntawm cov qe ntshav liab tau shrunken nrog ib tug notched ntug thaum raug rau ib tug heev ntsev tov, thaum plasmolysis yog cov txheej txheem ntawm cov nroj tsuag hlwb shrunken thaum raus hauv ib tug hypertonic tov. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm kev tsim thiab plasmolysis.
