Describe how apical meristem bring about growth in higher plants

  • The apical meristem consists of the tunica and corpus
  • The cells of the tunica region divide repeatedly by mitosis, perpendicular to the surface. This results in elongation of the shoot or root.
  • The corpus region cells divide by mitosis parallel to the surface. This increase the breadth of the stem
  • Apical meristem also produce auxins which promote cell division and elongation, resulting into increase in length or primary growth of the stem or roots
