叶绿体

Compared to the low drought-resistance BL-02-329, when subjected to drought stress, the net photosynthetic rate in the leaves of high drought-resistance alfalfa, Longdong, decreased more slowly and chloroplast shape and grana structure were less affected.

相对于抗旱性弱的苜蓿，抗旱性强的苜蓿随干旱胁迫程度的加深，净光合速率下降较慢，叶绿体的外形及基粒结构受到的影响较小。

Electron photomicrographs of individual chloroplasts at very high magnification show that they contain large numbers of layered substances, somewhat resembling stacked coins. These layers are known as grana.

从高倍放大的电子显微照片上可看到单个的叶绿体含有大量的一层层的像硬币一样重叠起来的物质，这些层状物被称作基粒。

Unsaturation of fatty acids in thylakoid membrane was accelerated, which might be helpful to stabilize photosynthetic apparatus. Distortion and swelling of grana caused by chilling in the dark probably decreased activities of antioxidant enzymes, which resulted in the accumulation of active oxygen species.

低温弱光胁迫对膜脂脂肪酸组成和叶绿体超微结构的影响均比暗中低温胁迫严重，而活性氧清除酶的活性有所下降，活性氧积累。

An example is the internal system of lamellae in CHLOROPLASTS.

例如，叶绿体内的片层基粒结构。

Their changes , as well as the stomatal opening response and the change of character in the lower epidermis are related to the overwintering ability.

叶绿体的破坏及修复、液泡膜的活动特点及质壁分离程度都表现出和物种越冬能力的相关性。

The primary resistances for CO2 diffusion are thought to be at the stomata and at photosynthesizing cells via a combination resulting from resistances of aqueous solution as well as the plasma membrane and both outer and inner chloroplast membranes.

CO2扩散速率的主要限制因素不仅与气孔和光合细胞中它的水溶性有关，还与质膜和叶绿体内外膜有关。

Ultrastructure observation revealed that the nuclei became deformed, nucleolus disintegrated and chromatin condensed, the thylakoids of chloroplast swelled, the chloroplast membrane disrupted, cristae of mitochondria disappeared and mitochondria vesiculated.

电镜观察发现，Cd(上标 2+)处理下，细胞核变形，核仁解体，染色质凝集；类囊体片层膨胀，叶绿体双层膜破裂；线粒体中嵴突减少或消失，线粒体空泡化。

DNA is a molecule that stores coded information. Another important nucleic acid—RNA—works in conjunction with DNA to bring about protein synthesis in cells.

DNA主要存在于细胞核内的染色质中，线粒体和叶绿体中也有，是遗传信息的携带者；RNA在细胞核内产生，然后进入细胞质中，在蛋白质合成中起重要作用。

Professor Daniel said that in order to produce anthrax vaccine, he will inject the vaccine gene into tobacco cells in the chloroplast genome.

丹尼尔教授说，为了制造出炭疽疫苗，他将疫苗基因注入到烟草细胞的叶绿体基因组中。

When oxygen is present in cells, polyphenol oxidase enzymes in the chloroplasts rapidly oxidize phenolic compounds naturally present in the apple tissues to o-quinones, colorless precursors to brown-colored secondary products.

当氧存在于苹果组织的细胞中时，叶绿体（含有叶绿素和进行光合作用的地方）中的多酚氧化酶，会迅速地将天然存在于苹果组织中的酚类化合物氧化为邻醌。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
