To make whole-wheat flour, the endosperm is combined with the bran and the germ. The bran is made up of the outer layers of the wheat kernel. Bran is used in whole-wheat flour. It is also used in breakfast cereals. The germ is the part that will sprout and grow into a new wheat plant if the kernel is planted.
Wheat germ is sold in grocery stores and food markets.
Whole wheat flour also contains wheat germ. Click here to see a picture of a Wheat Kernel close-up. This completes our wheat kernel close-up tour.
