The second reason light is important to organisms is that it is essential for photosynthesis.

The leaf was allowed to photosynthesize in the presence of radiocarbon.

叶子被允许同放射性碳进行光合作用.

The plant can then reach the light faster and photosynthesize and synthesize more chlorophyll.

这种植物被置于光下后,可迅速的开始光合作用,合成大量叶绿素.

Leaf area is the best measure of the photosynthesizing capacity of the plant.

叶面积是测定植株光合能力的最好尺度.

Chloroplasts are the site of photosynthesis in plants and other photosynthesizing organisms.

叶绿体是植物和其它光合作用有机体发生光合作用的场所.

So the controlling factor of photosynthetic rate was non-stomatal limitation.

白玉兰光合速率控制因子为 非 气孔限制.

The photosynthetic unit then is a physiological unit of function defined by experiments with intact plants.

通过用整体植物作的试验,又把光合单位定义为生理学的功能单位.

Water stress promoted allocation of photosynthetic product to the seed.

因此,水分胁迫促进了光合产物向籽粒的调运.

In some plants photosynthetic products are stored in the form polyfructosans.

在有些植物中,光合作用产物是以多聚果糖的形式储藏.

The photosynthetic pigment in bacteria is bacteriochlorophyll.

细菌光合作用的色素是细菌叶绿素.

Scientists invented a mosquito-repellent device using mosquito's phototaxis.

利用蚊子的趋光性,专家发明了一种灭蚊器.

Water beetles can swim in water, fly in the air, and have strong phototaxis.

龙虱在水能游, 出水能飞, 并有很强的趋光性.

Leaves are always positively phototropic.

叶子总是正向光性的.

Because the quality of the original manuscript determines the quality of phototypesetting film.

因为草稿的质量凹凸不决了照排片的质量短不幼.

Phototypesetting equipment could also reduce costs in other areas.

照相排版设备也可以在其他的区域中减少费用.

This process of converting light ( photons ) to electricity ( voltage ) is called the photovoltaic ( PV ) effect.

这个把光 ( 光子 ) 转化成电 ( 电压 ) 的过程被称作 光伏 效应.
