Growing Vegetables Without Soil Inside the Home
Have you ever wanted to grow your own food inside your home?
Scientists in Finland have developed a device that may do just that.
It lacks soil and does not look like a normal vegetable garden. But, the small device, called the Cell Pod, grows edible plant cells in the home.
Lauri Reuter is a biologist with the VTT Technical Research Centre of Finland. He says that instead of using the complete plant as food, scientists take only a small part of it – cells – and grow them in a bio-reactor. These plants have much of the same nutritional value that a real plant has.
The edible plant cells, once fully grown, do not look very good. The Finnish researchers say they also need to improve the taste.
However, the Cell Pod can provide important vitamins and antioxidants, which are substances that help your body to be healthy.
Lauri Reuter adds that the new technology will not replace fields for growing fruits and vegetables. However, the Cell Pod can help people eat foods that are hard to find or that cannot be made in a sustainable way. In other words, the device could help save natural resources.
All you would need to do is add the seed culture to the device, sit back and then wait.
Reuter says the seed culture looks a lot like a very small container filled with coffee. You put it into the device and give it water. The machine does the rest of the work.
The researchers hope to have a version of the Cell Pod on the market in the next 10 years.

内容解析
1.All you would need to do is add the seed culture to the device, sit back and then wait.
sit back 休息；不采取行动
Perhaps now they can sit back and rest on their oars.
也许现在他们可以坐下来休息一下了。
Then all we have to do is sit back and pick up the pieces.
我们所要做的就是等着收拾残局。
2.In other words, the device could help save natural resources.
In other words 换言之
In other words, you need to succinctly state what your application does.
换句话说，您需要简洁地描述应用程序完成的工作。
In other words, the country would abstain from a resolution favouring a cease-fire in place.
换言之，对于一项赞同就地停火的协议，那个国家将投弃权票。

无土栽培 在家也能种植绿色蔬菜
你是否想过自己在家里种食物？
芬兰科学家研发的一种设备能够实现这一愿望。
该设备没有土壤，看起来并不像普通的菜园子。然而，这个被称为“Cell Pod”的小型设备可以让你在家培育可食用植物的细胞。
罗力·罗伊特（Lauri Reuter）是芬兰国家技术研究中心的生物学家。他说，科学家只采集一小部分食物植物细胞，将其放置于生物反应器中培育。这些植物的营养价值与真实植物无异。
发育完成的可食用植物细胞，其外形并不美观。芬兰研究人员称，可食用植物的口感仍需进一步改善。
然而，Cell Pod可以提供重要的维生素和抗氧化剂，这些是维持身体健康的重要物质。
罗力·罗伊特还表示，这项新技术不会取代水果和蔬菜。然而，Cell Pod可以让人们食用一些稀有或者无法用可持续方式种植的食物。也就是说，该设备能够节约自然资源。
你只需要把种子放置在设备中，然后静静地等待就可以了。
罗伊特称，种子看起来就像一个装满咖啡的小容器。你把它放置到设备里，浇点水。该设备会自动完成剩下的工作。
研究人员希望10年内能在市场上推出Cell Pod。
