WITHIN A PLANT

It's quarter past seven. Here’s Worker No. 55 in his green uniform. He’s going to start work in the plant.

He works in Workshop 1001 in the Leaf. There are 20 to 100 workers in each workshop. They collect sunlight and CO2 during the day. Now workers from the Root send up water. The water will rise up to the Leaf through the Stem. Then workers in the Leaf will mix water, CO2, and sunlight.

What are they going to produce? Most importantly (for them), there will be sugar! It’s useful for the growth of the plant. Another product will be oxygen, but the plant doesn’t need much of it. It means a lot to animals and humans, though—they need it to breathe!

The workers work hard. Soon it’s going to get dark. They will take a rest.

There are millions of plants on Earth. They give more than food and oxygen. Without plants, the natural world would be very different!

在植物工厂内部

现在是七点十五分。工人55号穿着绿色的制服，准备开始在工厂工作。

他在“叶子车间1001”工作。每个车间有20到100名工人。他们白天收集阳光和二氧化碳。现在，“根部车间”的工人送来了水。水会通过“茎干”上升到“叶子车间”。然后，“叶子车间”的工人会把水、二氧化碳和阳光混合在一起。

他们要生产什么呢？最重要的是，他们会生产糖！糖对植物的生长非常有用。另一个产品是氧气，但植物不需要太多氧气。不过，对动物和人类来说，氧气非常重要——他们需要氧气来呼吸！

工人们努力工作。天快黑了，他们也要休息了。

地球上有成千上万的植物。它们不仅提供食物和氧气。没有植物，自然界将会非常不同！
