| Simple diagram of the dry grain showing its principle parts; the endosperm, aleurone and seed coat, the scutellum and the embryo with its primordial shoot and root. During grain milling these tissues are crudely separated: the endosperm becomes the white flour, the embryo is the germ and the aleurone layer and the seed coat are the bran. The seed coat is a complex structure. The Cell Layers inside the Grain are described in detail in a separate section. | |
