The soybean (or soya bean) is a plant with fruit called beans, from Eastern Asia. The height of a grown soybean is between less than 20 centimetres and up to 2 metres. One soybean lives for only one year.
Soybean oil has a component of oleic acid that can be used to make an insect repellent. Also fuel can be made from soybeans.
Soybeans can also be fermented to make nattō.
In 1997, 81% of all soybeans were of genetically modified stock. This means that genes were changed directly.
