A lamella (plural: " lamellae ") hauv biology hais txog ib txheej nyias nyias, daim nyias nyias, los yog phaj ntawm cov ntaub so ntswg. Lwm qhov piv txwv ntawm cellular lamellae , tuaj yeem pom hauv chloroplasts . Thylakoid membranes yeej yog ib qho system ntawm lamellar membranes ua hauj lwm ua ke, thiab sib txawv rau hauv txawv lamellar thaj chaw.
Hais txog qhov no, lub luag haujlwm ntawm lamella hauv chloroplast yog dab tsi?
Grana ua haujlwm hauv lub teeb pom kev ntawm photosynthesis. Lamella: Ib daim ntawv zoo li daim nyias nyias nyob hauv ib lub chloroplast ntawm ib qho autotrophic cell . Lawv ua raws li hom phab ntsa uas chloroplasts tuaj yeem kho tau hauv, ua tiav lub teeb siab tshaj plaws.
Qhov thib ob, txoj haujlwm ntawm stroma lamellae yog dab tsi? yog lub hollow raj zoo li channel uas yog khub nrog ib pawg ntawm thylakoids ( Granum ). Nws thauj cov khoom noj khoom haus thiab cov khoom tsim nyog rau thylakoids txhawm rau ua kom lub cev muaj sia nyob thiab ua haujlwm.
Ib yam li ntawd, lamella nyob rau hauv cov nroj tsuag yog dab tsi?
Qhov nruab nrab lamella yog ib txheej uas cements lub cell phab ntsa ntawm ob adjoining cog cell ua ke. Nws yog thawj txheej txheej uas tau tso rau lub sijhawm ntawm cytokinesis. Nyob rau hauv ib tug paub tab cog cell nws yog txheej txheej ntawm phab ntsa cell. Hauv nroj tsuag , pectins tsim ib qho kev sib koom ua ke thiab txuas ntxiv ntawm cov hlwb uas nyob ib sab.
Dab tsi yog qhov txawv ntawm grana lamellae thiab stroma lamellae?
Cov lamellae uas yog granum hauv chloroplast yog hu ua granal lamellae los yog thylakoids. Cov grana stacks khoom plig hauv stroma yog interconnected los ntawm membranous lamellae lub npe hu ua stroma lamellae.

Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Peb tuaj yeem pom dab tsi hauv stroma ntawm chloroplast?
Stroma feem ntau yog hais txog cov kua dej uas muaj nyob rau sab hauv ntawm chloroplasts nyob ib puag ncig thylakoids thiab grana.Txawm li cas los xij nws tam sim no paub tias cov stroma muaj cov hmoov txhuv nplej siab, chloroplast DNA thiab ribosomes, nrog rau tag nrho cov enzymes xav tau rau lub teeb ywj pheej ntawm photosynthesis, tseem hu ua Calvin voj voog
Dab tsi yog tsib lub hauv paus Circuit Court Cheebtsam lawv lub tsev yog dab tsi?
Cov no yog cov feem ntau siv: resistors. Capacitors. LEDs. Transistors. Inductors. Integrated Circuits
Dab tsi ntawm tib neeg lub cev zoo li chloroplast?
Chloroplast yog cov organelles uas nqus lub zog ntawm lub teeb thiab hloov nws mus rau chemical zog thaum lub sij hawm photosynthesis. Tib neeg lub qhov muag zoo li chloroplast vim hais tias, txawm hais tias lawv tsis ntes lub zog, qhov muag ntes lub teeb thiab nrog kev pab ntawm lub hlwb ua duab
