Qhov sib txawv tseem ceeb ntawm hypotonic thiab hypertonic yog tias cov tshuaj hypotonic muaj cov ntsiab lus tsis tshua muaj siab dua li ntawm tes thaum cov tshuaj hypertonic muaj cov kua dej ntau dua li ntawm tes.
Osmosis yog cov txheej txheem ntawm kev hloov cov dej molecules los ntawm cov dej muaj peev xwm mus rau cov dej tsis tshua muaj peev xwm los ntawm cov khoom siv semi-permeable. Txawm li cas los xij, qhov no semi-permeable membrane tsuas yog tso cai rau cov khoom hnyav (dej molecules) txav mus los ntawm nws thiab tsis tso cai rau cov kua dej txav mus los ntawm daim nyias nyias. Tonicity yog ib qho kev ntsuas ntawm osmotic siab gradient thiab muaj peb lub xeev ntawm nws. Cov no yog hypertonic, isotonic thiab hypotonic. Ntawm peb txoj kev daws teeb meem, cov tshuaj hypotonic yog cov tshuaj uas muaj cov ntsiab lus tsis tshua muaj siab thaum cov tshuaj hypertonic yog cov tshuaj uas muaj cov kua qaub siab. Qhov hnyav concentration gradient hla ob txoj kev daws teeb meem yog lub zog tsav rau cov txheej txheem no. Lub net txav ntawm cov kuab tshuaj los ntawm cov kuab tshuaj hypotonic mus rau hypertonic hnyav tshwm sim vim qhov tsis sib xws osmotic siab.
Hypotonic yog dab tsi?
Ib lub tshuaj hypotonic yog cov tshuaj uas muaj cov ntsiab lus tsawg dua piv rau sab hauv ntawm tes. Li no, lub siab osmotic ntawm cov tshuaj no yog tsawg heev piv rau lwm cov kev daws. Thaum ib lub xovtooj nkag mus rau hauv cov tshuaj hypotonic, cov dej molecules txav mus rau hauv lub cell los ntawm cov tshuaj vim yog lub peev xwm osmotic.
Daim duab 01: Kev daws teeb meem Hypotonic
Kev sib txuas ntawm cov dej molecules mus rau hauv lub cell yuav ua rau lub cell o. Thiab, nws yuav ua rau cytolysis ntawm tes (rupture). Txawm li cas los xij, cov nroj tsuag tsis tawg vim lawv muaj phab ntsa ntawm tes.
YHypertonic yog dab tsi?
A cov tshuaj hypertonic muaj cov ntsiab lus siab ntawm cov kuab tshuaj ntau dua li ntawm sab hauv ntawm tes. Thaum ib lub xovtooj nkag mus rau hauv cov tshuaj hypertonic, cov dej molecules tawm ntawm lub xovtooj mus rau cov tshuaj. Vim cov dej txav ntawm lub xovtooj mus rau sab nraud, lub xovtooj ntawm tes yuav tawg thiab wrinkled. Yog li, cov nyhuv no yog hu ua 'crenation' ntawm tes.
Daim duab 02: Hypertonic Solution
Nyob rau hauv cov nroj tsuag, cov plasma hloov pauv tau rub tawm ntawm phab ntsa ntawm tes, tab sis tseem koom nrog cov phab ntsa ntawm tes ntawm qee cov ntsiab lus vim yog cov nyhuv ntawm crenation thiab thaum kawg ua rau muaj mob hu ua 'plasmolysis'.
Dab tsi zoo sib xws ntawm Hypotonic thiab Hypertonic?
- Hypotonic thiab hypertonic yog ob hom kua dej ntxiv uas tau piav qhia txog osmolarity.
- Ob txoj kev daws teeb meem muaj cov kuab tshuaj molecules thiab solute molecules.
- Nyob rau hauv ob qho kev daws teeb meem, muaj kev txav ntawm cov kuab tshuaj molecules.
Qhov txawv ntawm Hypotonic thiab Hypertonic yog dab tsi?
Ib tshuaj hypotonic yog ib qho kev daws teeb meem uas muaj cov ntsiab lus tsis tshua muaj siab thaum cov tshuaj hypertonic yog cov tshuaj uas muaj cov kua qaub siab. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm hypotonic thiab hypertonic. Tsis tas li ntawd, cov tshuaj hypotonic muaj peev xwm dej siab thaum cov tshuaj hypertonic muaj peev xwm dej tsawg. Yog li, qhov no kuj yog qhov sib txawv tseem ceeb ntawm kev daws teeb meem hypotonic thiab hypertonic.
Ntxiv mus, qhov sib txawv ntxiv ntawm cov tshuaj hypotonic thiab hypertonic yog tias cov dej molecules txav los ntawm cov tshuaj hypotonic mus rau ntawm tes thaum cov dej molecules txav ntawm lub cell mus rau cov tshuaj hypertonic. Tsis tas li ntawd, cov hlwb ntsws ntsws thaum muab tso rau hauv cov tshuaj hypertonic thaum lub hlwb o thaum muab tso rau hauv cov tshuaj hypotonic. Yog li, qhov no kuj yog qhov sib txawv tseem ceeb ntawm hypotonic thiab hypertonic.
Cov ntaub ntawv hauv qab no nthuav tawm cov ntaub ntawv ntau ntxiv ntawm qhov sib txawv ntawm cov tshuaj hypotonic thiab hypertonic, sib piv.
Summary – Hypotonic vs Hypertonic
Hypotonic thiab hypertonic yog ob hom kev daws teeb meem raws li osmolarity. Ib qho kev daws teeb meem hypotonic muaj qhov tsis tshua muaj kuab concentration piv rau lub cell sab hauv. Yog li, dej molecules txav los ntawm cov tshuaj hypotonic mus rau lub cell. Vim cov dej txav mus rau hauv cov hlwb, cov hlwb o. Ntawm qhov tod tes, ib qho kev daws teeb meem hypertonic muaj cov ntsiab lus siab siab piv rau ntawm tes. Yog li ntawd, cov dej molecules txav ntawm lub cell mus rau cov tshuaj. Raws li qhov tshwm sim, cov hlwb yuav txo qis. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm hypotonic thiab hypertonic.
