A grain has 3 parts: a germ, an endosperm, and a bran.

True. A grain, also known as a cereal grain, is the edible seed of a grass plant and typically consists of three parts: the germ, endosperm, and bran. The germ is the embryo or sprouting section of the seed, the endosperm is the starchy part that provides energy to the growing plant, and the bran is the outer layer that contains fiber, vitamins, and minerals. Whole grains contain all three parts, while refined grains have had the bran and germ removed during processing.
