discuss secondary growth of roots in dicot plants

Roots of a dicot plant have vascular cambium and cork cambium that undergo divisions to produce secondary tissue. Inner cells of the vascular cambium undergo divisions to form secondary xylem and outer cells of the vascular cambium undergo divisions to form secondary phleom. Cells of the cork cambium divide to form cork (outer layer of the root). Both vascular and cork cambium divide to increase the width of root.

these points will help u 2 undrstand simply..

  • the conjunctive tissue inner 2 the phloem becomes meristematic to form Cambium..
  • the pericycle cells outside the protoxylem becomes meristematic to form a strip of cambium..
  • these cambial strips unite 2 form a wavy cambial ring.
  • the cells of the cambial ring cut off cells towards the outer side and inner side..
  • the cells formed outside become secondary phloem and that towards inside become secondary xylem..

thumb up, if u got it..
