Have you ever wanted to grow your own food inside your home? Scientists in Finland have developed a device(设备) that may do just that.

Unlike a usual vegetable garden, it doesn’t need soil. But, the small device, called the Cell Pod, grows plant cells which are safe to eat in the home.

Lauri Reuter, a biologist, 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(生物反应器). These plants have much of the same nutritional(营养的) value that a real plant has. The plant cells which are safe to eat, 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 things that help your body to be healthy.

Lauri Reuter adds that the new technology will not be instead of fields for growing fruits and vegetables. However, the device could help save natural resources. All you would need to do is add the seed culture(培养物) to the device, give it water, sit back and then wait. The machine does the rest of the work.

The researchers hope to have a form of the Cell Pod on the market in the next ten years.
