Photosynthesizing organisms cast a green glow across the sweep of the ice.

进行光合作用的生物在冰原上投下一缕绿色。

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。

The index is high in areas where plants are dense, with plenty of photosynthesizing leaves.

在植被茂密，有着大量光合作用树叶的地区，该指数较高；

The bathyal zone is the dimly lit middle zone, which because it has little sunlight does not contain photosynthesizing producers.

半深海区是微暗发亮的中央地域，因为它没有进行光合作用生产者。

By measuring the photon signatures left when light bounces off photosynthesizing cells, astronomers may soon have a new tool for detecting extraterrestrial organisms.

通过测量光线从光合作用细胞反射后遗留下来的光子标记，天文学家们可能很快就能拥有一种新的探测外星生命的工具了。
