广播电视英语短句 第 214 课：植物如何使用水-1

Scientists have discovered more details about how plants use water. 科学家们已经发现植物如何使用水的更多的细节。

Their findings could help to engineer plants that grow better and more effectively in conditions with higher level of carbon dioxide. 他们的发现有助于促进植物在高二氧化碳条件下长处更好、更有效。

Plants naturally take in carbon dioxide they need for photosynthesis, the process of changing light energy to chemical energy. 植物在自然状况下吸收他们光合作用所需的二氧化碳，这一过程把光能转化为化学能。

The carbon dioxide enters the plants through tine hollows or pores on the surfaces of leaves. 二氧化碳通过小孔或者叶面上的孔进入植物。

However, each time of plants take in one molecule of carbon dioxide gas, it losses hundreds of water molecules. 然而，当每次植物吸收一个二氧化碳气体分子时，它会损失许许多多的水分子。
