Hauv feem ntau cov nroj tsuag siab dua, cov thylakoids tau npaj nruj pawg hu ua grana (singular granum). Grana txuas nrog stromal lamellae, txuas ntxiv uas khiav los ntawm onegranum, dhau los ntawm stroma, mus rau hauv ib cheeb tsam ze.

Cov lus nug tseem yog, Grana hauv chloroplast yog dab tsi?

A thylakoid yog ib tug membrane-bound compartmentinside chloroplasts thiab cyanobacteria. Chloroplast thylakoids feem ntau tsim pawg ntawm cov disks hu ua grana (singular: granum). Grana txuas nrog intergranal los yog stroma thylakoids, uas koom nrog granum stacks ua ke ua ib qho chaw ua haujlwm.

Qhov thib ob, Granum zoo li cas? A granum yog npib- zoo li tus pawg ofthylakoids, uas yog lub membrane- nyiam Cov qauv muaj nyob rau hauv cov chloroplasts ntawm cov nroj tsuag. Grana, los yog pawg ntawm granum , yog txuas los ntawm txoj kev ntawm stromal thylakoids. The grana ua kom cov cheeb tsam ntawm cov thylakoids.

Ib sab saum toj, vim li cas Thylakoids stacked rau hauv grana?

Chloroplasts muaj cov txheej txheem ntawm cov hnab ntim khoom, cov thylakoids , ib co stacked ua form grana (singular, granum), whereas lwm tus ntab dawb hauv lub stroma. Nws nyob ntawm thylakoid membranes uas cov electron cab kuj tsim nyog rau photosynthesisreside.

Thylakoid yog dab tsi?

Lub stroma muaj ribosomes, enzymes, thiab chloroplastDNA. Cov thylakoid muaj cov thylakoid membrane thiab lub cheeb tsam uas nyob ib puag ncig hu ua thylakoid lumen. Ib stackof thylakoids tsim ib pab pawg ntawm npib zoo li cov qauv hu ua agranum. Ib qho chloroplast muaj ntau yam ntawm cov qauv no, sib sau ua ke hu ua grana.
