Plasma Membrane Txhais . Cov plasma daim nyias nyias ntawm a cell yog lub network ntawm lipids thiab cov proteins uas tsim cov ciam teb ntawm a cell cov cov ntsiab lus thiab sab nraud ntawm lub cell . Nws kuj tseem hu ua tus cell membrane . Nws yog semi-permeable thiab tswj cov ntaub ntawv uas nkag mus thiab tawm ntawm lub cell.

Tib neeg kuj nug, dab tsi yog plasma membrane yooj yim txhais?

Cov cell membrane yog ib txheej nyias nyias nyob ib ncig ntawm lub hlwb ntawm txhua yam muaj sia. Nws yog qee zaum hu ua plasma daim nyias nyias los yog cytoplasmic daim nyias nyias . Nws yooj yim txoj haujlwm yog cais cov cell sab hauv los ntawm sab nraud. Nyob rau hauv tag nrho cov cell cell membrane cais cov cytoplasm sab hauv cell los ntawm nws ib puag ncig.

Ib tug kuj yuav nug, dab tsi yog cov plasma membrane? Cov plasma daim nyias nyias , kuj hu ua cell daim nyias nyias , yog daim nyias nyias pom nyob rau hauv tag nrho cov hlwb uas cais cov sab hauv ntawm lub cell los ntawm sab nraud ib puag ncig. Cov plasma daim nyias nyias Nws muaj cov lipid bilayer uas yog semipermeable. Cov plasma daim nyias nyias tswj kev thauj cov khoom nkag thiab tawm ntawm lub cell.

Hauv qhov no, lub cell membrane luv txhais li cas?

Qhov nyias daim nyias nyias uas ua rau sab nrauv ntawm lub protoplasm ntawm a cell thiab tswj kev nkag mus ntawm cov ntaub ntawv nyob rau hauv thiab tawm ntawm lub cell . Nws yog tsim los ntawm cov proteins thiab lipids thiab feem ntau muaj molecular receptors. Cov daim nyias nyias organelles nyob rau hauv lub cev cell yog ua los ntawm tib yam khoom siv raws li cov cell membrane.

Vim li cas nws thiaj li hu ua plasma membrane?

Cov ntshav ntshav yog "filling" ntawm lub cell , thiab tuav cov cell cov organelles. Yog li, sab nraud daim nyias nyias ntawm cell yog qee zaum hu ua tus cell membrane thiab qee zaum hu ua tus plasma daim nyias nyias , vim hais tias yog dab tsi nws yog nyob rau hauv kev sib cuag nrog. Yog li ntawd, tag nrho cov hlwb yog surrounded los ntawm ib tug plasma daim nyias nyias.
