Qhov sib txawv tseem ceeb ntawm tonoplast thiab plasma membrane yog tonoplast yog daim nyias nyias uas kaw lub hauv paus vacuole ntawm cov nroj tsuag cell thaum lub plasma membrane yog daim nyias nyias uas kaw lub cytoplasm ntawm ib lub xovtooj.
Ib lub xovtooj yog lub hauv paus txheej txheem thiab kev ua haujlwm ntawm cov kabmob muaj sia. Qee cov kab mob yog unicellular, hos ntau yog multicellular. Ib lub cell muaj cov khoom sib txawv. Lub cell membrane, cytoplasm, cellular organelles, vacuoles thiab tonoplast yog ob peb yam xws li. Lub cell membrane yog tus ciam teb ntawm cov cell uas cais cov cell plasma los ntawm nws qhov chaw sab nrauv. Txawm li cas los xij, cov nroj tsuag muaj cov phab ntsa ntawm tes sab nrauv rau cov cell membrane. Tonoplast yog daim nyias nyias uas kaw lub vacuole ntawm lub cell, tshwj xeeb tshaj yog nyob rau hauv cov nroj tsuag cell. Hauv lwm lo lus, nws yog lub vacuolar membrane ntawm cov nroj tsuag. Ob leeg tonoplast thiab plasma membrane tso cai rau cov dej thiab cov kuab tshuaj txav mus hla lawv.
Tonoplast yog dab tsi?
Cov noob qes muaj lub vacuole loj nyob hauv nruab nrab ntawm lub xovtooj, thiab nws yog lub luag haujlwm rau turgor siab. Yog li ntawd, vacuole tswj cov turgor siab nyob rau hauv cov nroj tsuag thiaj li yuav tswj tau ib tug nruj nroj tsuag qauv. Tonoplast yog hom tshwj xeeb ntawm daim nyias nyias uas nyob ib puag ncig lub hauv paus vacuole ntawm cov nroj tsuag. Nws tseem hu ua vacuolar membrane.
Daim duab 01: Tonoplast
Vim tias tsuas yog cov hlwb cog muaj cov tonoplast, tonoplast yog cov qauv tshwj xeeb rau cov nroj tsuag. Nws yog ib qho semi-permeable membrane uas tso cai rau xaiv hom ions thiab cov khoom nkag mus rau hauv thiab tawm. Los ntawm kev ua raws li kev thaiv ntawm cytoplasm thiab cov ntsiab lus ntawm lub vacuole, nws tswj kom muaj qhov sib npaug ntawm cov as-ham thiab ions sab hauv thiab sab nraud ntawm lub vacuole. Muaj cov twj proton xws li proton-ATPase thiab proton-pyrophosphatase nyob rau hauv lub tonoplast. Cov twj tso kua mis proton pab tswj lub siab turgor.
Plasma Membrane yog dab tsi?
Plasma membrane lossis cell membrane yog cov kab mob lom neeg uas kaw cov cytoplasm ntawm lub cell. Nws cais cov sab hauv ntawm tes los ntawm ib puag ncig sab nraud. Los ntawm kev ua ib qho kev thaiv ntawm sab hauv thiab sab nrauv ntawm tes, nws tiv thaiv lub cell sab hauv. Ntxiv nrog rau kev tiv thaiv, cov plasma membrane tseem ua kom yooj yim rau kev xa cov teeb liab thiab cov cellular thauj ntawm ions thiab lwm yam khoom. Lub plasma membrane yog ib tug semi-permeable membrane uas tso cai rau xaiv cov khoom nkag mus thiab tawm ntawm lub cell. Kev txav ntawm cov molecules hla cov daim nyias nyias tuaj yeem tshwm sim dhau los lossis ua haujlwm.
Daim duab 02: Plasma Membrane
Structurally, plasma membrane yog tsim los ntawm lipid bilayer. Nws kuj muaj cov proteins nyob rau saum npoo, hla hla daim nyias nyias thiab txuas los ntawm sab hauv. Ntxiv nrog rau phospholipids thiab cov proteins, plasma membrane muaj cov roj cholesterol thiab carbohydrate molecules. Cov qauv dej mosaic yog cov qauv uas piav qhia txog cov qauv ntawm cov plasma membrane uas muaj cov mosaic ntawm cov khoom. Cov roj (cholesterol) molecules ua rau cov kua dej ntawm daim nyias nyias.
Dab tsi zoo sib xws ntawm Tonoplast thiab Plasma Membrane?
- Tonoplast thiab plasma membrane yog daim nyias nyias uas kaw cov vacuole thiab cytoplasm, feem.
- ob leeg yog ib daim nyias nyias.
- Tonoplast thiab plasma membrane yog tsim los ntawm lipid bilayer.
Qhov txawv ntawm Tonoplast thiab Plasma Membrane yog dab tsi?
Tonoplast yog ib qho permeable membrane uas kaw lub hauv paus vacuole nyob rau hauv ib lub cell cell thaum lub plasma membrane yog ib tug semi-permeable phospholipid bilayer uas encloses lub cytoplasm ntawm tag nrho cov hlwb. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm tonoplast thiab plasma membrane. Yog li, lub tonoplast cais cov ntsiab lus ntawm vacuole los ntawm cytoplasm thaum plasma membrane cais qhov chaw sab nraud ntawm cytoplasm.
Ntxiv mus, tonoplast yog qhov tshwj xeeb rau cov nroj tsuag, tab sis cov plasma membrane pom nyob rau hauv txhua hom hlwb. Functionally, tonoplast tswj turgor siab, thiab nws tswj lub zog ntawm ion nyob rau hauv thiab tawm lub vacuole. Meanwhile, cell membrane tswj kev txav ntawm cov tshuaj nyob rau hauv thiab tawm ntawm lub hlwb, koom nyob rau hauv lub cell adhesion, ion conductivity thiab cell signaling thiab ua hauj lwm raws li ib tug txuas nto rau ob peb extracellular lug. Yog li, qhov no yog qhov ua haujlwm sib txawv ntawm tonoplast thiab plasma membrane.
Hauv qab infographic qhia txog qhov sib txawv ntawm tonoplast thiab plasma membrane.
Summary – Tonoplast vs Plasma Membrane
Tonoplast yog daim nyias nyias uas nyob ib puag ncig lub hauv paus vacuole ntawm cov nroj tsuag cell. Txawm li cas los xij, plasma membrane yog daim nyias nyias uas nyob ib puag ncig cytoplasm ntawm txhua lub hlwb. Qhov no yog qhov sib txawv tseem ceeb ntawm tonoplast thiab plasma membrane. Txawm li cas los xij, ob qho tib si tonoplast thiab plasma membrane yog phospholipid bilayers. Lawv ua raws li semi-permeable daim nyias nyias thiab tso cai rau lub zog ntawm ions thiab molecules xaiv nkag mus rau sab hauv thiab sab nraud los ntawm lawv.
