Distribution of the division walls of all of the cells (a, d) and apical initials only (b, e), in the case of the initials with the angular orientation of their walls (c, f). The results come from two simulations in which the surface cell layer originated from the uniform (a–c) and not uniform (d–f) initials (Fig. 5a, b, respectively). The distributions a and d show the picture as observed from the top view, but the walls are normalized to have the same length. In b, e, the normalized division walls are magnified to be the same scale as the incoming initials In1 and In2
