Rice is a grain that is a staple food for over half the world. It is a cereal grain and a member of the "Oryza" genus. The plant is harvested and grown in many parts of the world, including Asia, Africa, and North America. Rice is grown in water, as it cannot grow in dry soil. Rice can be boiled, baked, or fried. It can be used in rice pudding, soups, or rice noodles.
