Question

discuss secondary growth of roots in dicot plants

Answer 1

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.
