Wheat is our most common grain and has been cultivated as a food source for over 10,000 years, according to archaeological records. As a crop, wheat has the largest land area of any other crop in the world. So to say that wheat is important would be an understatement. Technically, the wheat plant is a grass and is cultivated for its seeds, and this seed, called a wheat berry, is the most important cereal grain in the world today. Though there are many species of wheat, the most prevalent is called common wheat and will be what we use for our references today. The wheat berry is made up of three partsthe bran, the germ, and the endosperm. These are not extremely important for our purposes today, but it is important to know there are different parts of the wheat berry.
