它们像小型的气泵,可将植物赖以生存的二氧化碳吸进植物体内并聚积起来。
It all acts as a miniature pump, sucking in and concentrating vital carbon dioxide.
《植物之歌》《How To Grow A Planet》
因此当空气中的二氧化碳含量变少时,草类便在植物界中略胜一筹。
So, although there was less carbon dioxide in the air, the grasses had the edge over other plants.
《植物之歌》《How To Grow A Planet》
光合作用就发生在这些叶片的细胞中,二氧化碳在这里与水发生反应形成糖类。
It's in the cells of the leaves that photosynthesis occurs, where carbon dioxide is combined with water to make sugar.
《植物之歌》《How To Grow A Planet》
它们有叶绿体。叶绿体把二氧化碳和水份与太阳光能量合成氧气与糖份,一种化学能量。
They have chloroplasts that combine carbon dioxide and water with light energy from the sun to create oxygen and sugar, a form of chemical energy.
《TED教育》《TED-Ed》
没关系,我一点问题都没有。我也没有幽闭恐惧症什么的。我们被困住了,我不能呼吸了,室内二氧化碳比氧气多,比率全都错了!
That's fine. I don't have a problem with that. I'm not claustrophobic or anything. We're trapped. I can't breathe. There's more carbon dioxide than oxygen! The ratio is all wrong!
