Corn Root Tissue

Corn is the common name for the cereal grass widely grown as food for humans and animals. Along with wheat and rice, it is one of the world's chief grain crops and the leading crop grown in the United States. Native to the Americas, corn (Zea mays), the domesticated variety of the Zea grass family, originally was cultivated by Native Americans 8,000 to 10,000 years ago and is now used for human food and animal feed.
