What is Corn?
Corn, also known as maize is a cereal grain that originated in southern Mexico. The kernels or seeds of corn are the edible parts. It can be eaten whole when it is very young and tender. But as it matures, the corncob or the part on which the kernels grow becomes harder and inedible. They come in multiple colors, depending on where they have grown and what species or variety they happen to be.
Sweetcorn is another genetic variant and it has more sugar and less starch in the nutritive material.
