Structure of Cereals
Figs. 1.36 and 1.37. Scanning electron micrograph of a cross section of a pearl millet kernel. (Reprinted from Badi et al 1976) 1.36. The opaque part. Note the air spaces and the spherical starch granules. 1.37. The vitreous part. Note the lack of air space, the polygonal starch granules, and the protein bodies (P).
The protein bodies have a well-defined internal structure, as shown by the pattern of electron scattering in transmission electron micrographs. Suggested Reading Bechtel, D. B., and Wilson, J.
