We propose to orient an embryo-in sagittal view-in such a way that the plumule is on the right of the root cap (which is itself then situated on the left), or in other words, such that the dorsal part of the embryo is on the left and the frontal part on the right (Fig.

There is also a reduction in the size of the root cap and derangement of the meristematic tissue, besides the formation of protoxylem and endoderm in regions close to the root apex with high contents of lignin (Miguel et al., 2010).
