Thylakoids feem ntau yog teem rau hauv pawg (grana) thiab muaj cov xim photosynthetic (chlorophyll). Thegrana txuas nrog rau lwm yam pawg los ntawm daim nyias nyias (lamellae) nyob rau hauv lub stroma, cov kua proteinaceous feem uas muaj cov enzymes tseem ceeb rau photosynthetic darkreaction, los yog Calvin voj voog.

Yog li ntawd, yog vim li cas cov Thylakoids stacked?

Chloroplasts muaj cov txheej txheem ntawm cov hnab ntim khoom, cov thylakoids , ib co stacked tsim grana (singular, granum), whereas lwm tus ntab dawb hauv lub stroma. Nws nyob ntawm thylakoid daim nyias nyias uas cov khoom siv hluav taws xob tsim nyog rau photosynthesis nyob.

Kuj Paub, dab tsi yog pawg ntawm grana txuas los ntawm? ua haujlwm hauv chloroplasts …Tight stacks hu ua grana (singular granum). Grana yog txuas los ntawm stromal lamellae, txuas ntxiv uas khiav los ntawm ib qho granum, dhau ntawm stroma, mus rau hauv ib lub granum nyob sib ze. Cov thylakoid membrane envelops lub hauv paus aqueous cheeb tsam hu ua lub thylakoid lumen.

Thiab cov lus nug yog, lub hom phiaj ntawm thylakoid membrane yog dab tsi?

Cov thylakoid daim nyias nyias ntawm ib tug chloroplast yog ib qho system ntawm interconnected daim nyias nyias , uas ua tawm lub teeb pom kev ntawm photosynthesis. Lawv tau teem caij rau hauv cheeb tsam thiab tsis muaj chaw hu ua grana thiab stroma thylakoids Raws li txoj cai, uas yog sib txawv enrichedin photosystem I thiab II complexes.

Cov Thylakoids puas muaj chlorophyll?

Cov tshuaj chloroplast muaj chlorophyll hauv nws thylakoids , uas absorbs lub teeb lub zog thiab muab chloroplasts nws cov xim ntsuab. Pawg ntawm thylakoids yog hu ua grana, uas muaj nyob rau hauv qhov chaw qhib ntawm chloroplast hu ua asthe stroma.
