Hardwood Defect Tutorial. The tip of the root is protected by the root cap, a structure exclusive to roots and unlike any other plant structure. For wood formation, the cells on the xylem side of the cambium pass through four sequential developmental stages: (1) division of the xylem mother cells, (2) expansion of the derivative cells to their final size, (3) lignification and secondary cell wall formation (i. e., cell maturation), and (4) programmed cell death (Uggla et al., 1996, 1998; Chaffey, 1999) (Fig. Other sets by this creator.
