 ""Two critical events must occur after the embryo proper forms: (i) regions along the longitudinal apical-basal axis must differentiate from each other and generate embryonic organ systems, and (ii) the three primordial tissue layers of the embryo need to be specified. Both of these events take place during the globular-heart transition phase (Fig. 2 and Table 1). The embryo proper has a spherical shape during the proembryo and globular stages (Fig. 2). The first visible cell differentiation events occur at the 16-cell stage when the protoderm, or outer cell layer of the embryo proper, is produced and the hypophysis forms at the top of the suspensor (Fig. 2). Subsequent cell differentiation events within the embryo proper result in the production of an inner procambium tissue layer and a middle layer of ground meristem cells (Fig. 2)."
