Grana (plural ntawm ' granum ') yog pawg ntawm cov qauv hu ua thylakoids, uas yog me me disks ntawm daim nyias nyias uas lub teeb-nyob ntawm kev cuam tshuam ntawm photosynthesis tshwm sim. Stacked rau hauv grana, cov duab ntawm cov thylakoids tso cai rau qhov chaw zoo tshaj plaws, ua kom cov photosynthesis ntau tshaj plaws uas tuaj yeem tshwm sim.

Ib yam li ntawd, tib neeg nug, dab tsi tshwm sim hauv Granum?

A granum yog ib lub npib zoo li pawg ntawm thylakoids, uas yog cov txheej txheem zoo li daim nyias nyias nyob hauv cov chloroplasts ntawm cov nroj tsuag. Photosynthesis, lossis cov txheej txheem uas cov nroj tsuag ua rau lawv tus kheej cov zaub mov, tshwm sim hauv chloroplasts. Lub grana ua kom nce thaj tsam ntawm thylakoids.

Kuj Paub, Thylakoids ua haujlwm yog dab tsi? Ib tug thylakoid yog ib daim ntawv zoo li daim nyias nyias-txheej txheem uas yog qhov chaw ntawm lub teeb-dependent photosynthesis Cov tshuaj tiv thaiv hauv chloroplasts thiab cyanobacteria. Nws yog qhov chaw uas muaj cov chlorophyll siv los nqus lub teeb thiab siv rau cov tshuaj biochemical.

Tom qab ntawd, Granum tsim li cas?

Cov granum txheej yog tsim los ntawm bifurcation thiab tom qab fusion ntawm daim nyias nyias es tsis yog los ntawm invagination los yog folding. Cov khaubncaws sab nraud povtseg hauv cov granum tsis txuas rau ib leeg los ntawm stroma lamellae.

Lub luag haujlwm ntawm grana thiab stroma yog dab tsi?

Lub grana ntawm chloroplast muaj cov xim uas ua los ntawm chlorophyll-a, chlorophyll-b, carotine thiab xanthophyll thaum lub stroma muaj cov enzymes tsim nyog rau photosynthesis zoo li DNA, RNA thiab cytochrome system.
