Vedclass · Answer

(C) In dicot roots, secondary growth occurs due to the activity of the vascular cambium and the cork cambium $(phellogen)$.As the secondary growth progresses over two or three years, the increasing girth of the root exerts pressure on the outer tissues.The epidermis and the cortex are gradually crushed and eventually sloughed off due to the formation of the periderm (cork, cork cambium, and secondary cortex) and the continuous expansion of the vascular tissues.Therefore, the cortex is largely lost as the root matures.

After two or three years of the secondary growth, what happens to the cortex in a dicot root?
