例句與用法
These stacks of thylakoids are called grana . 這些成堆的類囊體稱為質(zhì)體基粒。
Grana stacks have the interesting property of unfolding in low ionic strength medium . 在低離子強(qiáng)度介質(zhì)中,基粒垛疊能打開這是一個(gè)有意思的性質(zhì)。
With the light microscope these stacks are just visible as grains ( grana ) 可以用光學(xué)顯微鏡觀察到這些堆積成顆粒狀的物質(zhì)(質(zhì)體基粒) 。
The chloroplasts of the mesophyll , by contrast , appear normal and contain grana , but do not form starch grains 相比較而言,葉肉細(xì)胞內(nèi)的葉綠體數(shù)目少、含基粒,但不形成淀粉粒。
In all plants except algae , the thylakoids overlap at intervals to form stacks , like piles of coins , called grana 在除了藻類的所有植物中,許多圓盤狀的類囊體疊置成垛,稱為基粒。
The cells of the bundle sheath that surround the vascular tissues are large and contain specialized elongated chloroplasts that do not contain grana , but form starch grains 它的特點(diǎn)為:圍繞在維管組織外層的維管束薄壁細(xì)胞較大,并含有較大的葉綠體,這些葉綠體中不含基粒,但形成淀粉粒。
The photosynthetic pigments and accessory pigments are bound to these membranes , which also contain the components of the electron - transport chain and enzymes needed for the light - dependent reactions of photosynthesis 光合作用色素和一些色素附和物附在基粒的膜上,可能還包含有電子傳遞鏈的組分,以及光合作用光反應(yīng)所需的酶。
In addition , at the ultrastructure scale , there are evident differences in chloroplast . in lower salinity ( 50 , 100mm ) , the lamellae of stoma and grana in some chloroplast expanded lightly ; the boundary of the chloroplast was dim 在50 、 100mhnacl處理下,細(xì)胞中有些葉綠體的基質(zhì)、基粒片層稍有變形,被膜界限出現(xiàn)模糊現(xiàn)象,類囊體出現(xiàn)膨大。
During the process of senescence , the structural abnormality occurred firstly in chloroplast in which chloroplast grana disordered and stromal lamellae twisted and in which starch grains became bigger and osmiophilic granules increased , and then converged into bigger granules 葉綠體最早出現(xiàn)結(jié)構(gòu)異常:基粒結(jié)構(gòu)紊亂,基質(zhì)內(nèi)囊體發(fā)生扭曲、淀粉粒由小變大、嗜鋨顆粒由少變多再逐漸匯集成大的顆粒。
From green part , transition color part to yellow part of variegated leaf from h . " so sweet " , the changing ultrastructure of chloroplasts is roundness from ellipse , granum - thylakoid swelling , vesicle bringing and osmiophile globule adding 在花葉玉簪品種h . ‘ sosweet ’葉片的葉綠體超微結(jié)構(gòu)中,從綠色部分?過渡色部分?黃色部分出現(xiàn)由橢圓形轉(zhuǎn)變?yōu)閳A形、基粒類囊體腫脹、囊泡產(chǎn)生和噬餓顆粒增多的趨勢(shì)。
