Qhov Tseem Ceeb Qhov txawv - Grana vs Thylakoid
Cov noob qes, uas yog eukaryotic nyob rau hauv cov xwm txheej, muaj cov organelles sib txawv kom ua tiav nws txoj haujlwm raug. Chloroplast yog ib qho tseem ceeb organelle nyob rau hauv cov nroj tsuag cell thiab yog ib tug membrane khi organelle koom nyob rau hauv kev ua hauj lwm ntawm photosynthesis nyob rau hauv cov nroj tsuag; photosynthesis yog cov txheej txheem uas cov nroj tsuag tsim lawv cov zaub mov thiab lub zog los ntawm kev siv carbon dioxide, dej, hnub ci zog ntes los ntawm cov nroj tsuag xim - chlorophyll. Chloroplast yog tus kheej-replicating organelles thiab muaj sib txawv compartments nyob rau hauv lub organelle los pab txhawb nws cov dej num. Grana thiab thylakoids yog ob yam khoom muaj nyob rau hauv chloroplast thiab koom nrog lub teeb pom kev ntawm photosynthesis. Thylakoids yog daim nyias nyias compartments los yog disks qhov twg lub teeb tshwm sim tshwm sim. Grana yog cov pawg ntawm cov thylakoid disks tsim hauv chloroplast. Qhov no yog qhov sib txawv tseem ceeb ntawm grana thiab thylakoids.
Grana yog dab tsi?
Grana (qhov lus - Granum) yog pawg ntawm daim nyias nyias lub npe hu ua thylakoid daim nyias nyias, thiab lawv tau faib rau hauv stroma ntawm chloroplast. Lawv yog cov microscopic thiab tuaj yeem pom nyob rau hauv lub teeb pom kev zoo thiab cov duab oval. Lub grana txuas nrog lamellae, ib daim nyias nyias uas txuas cov grana, thiab tseem koom nrog cov txheej txheem teeb pom kev zoo.
Daim duab 01: Grana ntawm Chloroplast
Kev koom tes ntawm thylakoids rau hauv grana ua rau thaj chaw saum npoo rau lub teeb nyob ntawm photosynthesis hauv cov nroj tsuag, yog li ua kom cov txheej txheem ua haujlwm tau zoo.
YThylakoid yog dab tsi?
Thylakoids yog disk zoo li cov txheej txheem membranous uas muaj nyob rau hauv chloroplast stroma thiab yog lub ntsiab compartments uas koom rau hauv lub teeb nyob ntawm cov tshuaj tiv thaiv ntawm photosynthesis. Lawv yog cov microscopic thiab feem ntau pom los ntawm electron micrography. Lawv muaj cov khw muag khoom ntawm chlorophyll uas ntes lub hnub ci zog los pib lub teeb pom kev ntawm photosynthesis ntawm photosystems I thiab II. Thaum lub teeb tawm tsam cov xim no, lawv faib dej thiab tso oxygen los ntawm cov txheej txheem ntawm photolysis.
Daim duab 02: Thylakoids
Cov electrons tso tawm los ntawm cov tshuaj tiv thaiv no ntaus lub photosystem 2, thiab raug xa mus rau photosystem 1 ntawm electron nqa. Cov electrons tau zoo siab ntxiv thiab txhawb nqa rau lub zog siab dua. Lub tshuab nqa hluav taws xob NADP + tau txais cov hluav taws xob thiab raug txo rau NADPH, tsim ATP.
Dab tsi zoo sib xws ntawm Grana thiab Thylakoid?
- Grana thiab thylakoids nyob rau hauv chloroplasts stroma ntawm cov nroj tsuag hlwb.
- Ob leeg yog cov qauv siv tshuab.
- Ob leeg yog cov qauv membranous.
- Ob lub qauv muaj chlorophylls (cov xim cog qoob loo) rau photosynthesis.
- Ob lub qauv koom nrog hauv lub teeb pom kev ntawm Photosynthesis
Qhov txawv ntawm Grana thiab Thylakoid yog dab tsi?

Summary – Grana vs Thylakoid
Photosynthesis yog txheej txheem tseem ceeb rau kev tswj lub zog ntws hauv cov kab mob ntawm cov khoom noj. Nws yog tib txoj kev ywj pheej uas cov pa roj carbon dioxide tuaj yeem hloov mus rau cov piam thaj thiab lub zog. Chloroplast yog qhov chaw ntawm photosynthesis, qhov twg hnub ci hloov mus rau hauv cov zaub mov los ntawm cov nroj tsuag. Cov txheej txheem no yog ua nyob rau hauv ob txoj kev tseem ceeb: lub teeb nyob rau hauv cov tshuaj tiv thaiv thiab lub teeb ywj siab los yog qhov tsaus ntuj. Grana yog thylakoids yog ob lub qauv hauv chloroplasts uas koom nrog hauv photosynthesis. Thylakoids yog tus naj npawb ntawm cov hnab ntim flattened hauv chloroplast, khi los ntawm cov xim pigmented uas lub teeb pom kev ntawm photosynthesis tshwm sim. Grana yog cov pawg ntawm thylakoids teeb tsa hauv stroma kom nce thaj chaw saum npoo rau lub teeb nyob ntawm photosynthesis. Lub teeb nyob ntawm qhov tshwm sim ntawm photosynthesis feem ntau tshwm sim hauv thylakoid daim nyias nyias. Qhov no yog qhov txawv ntawm grana thiab thylakoid.
