    site of mitosis
  7. apical meristem
    length
  8. lateral meristem
    width
  9. elongation zone
    site of growth
  10. maturation (differentiation) zone
    site where cells become specialized
  11. hairs on roots
    increase surface area for absorption
  12. root cap
    protects and lubricates growing roots
  13. vascular tissue of roots
    • xylem
