Solution :-

Periderm is a protective layer present outside the stem that replaces the epidermal layer in response to any injury or invasion of pathogens. Phelloderm, phellogen, and phellem together constitute the periderm. Dicot stems produce phellogen or cork cambium in the external cortical cells. Phellogen cells split on both the inner side and the outer side to form secondary tissues. The secondary tissue produced on the inner side of the phellogen is known as the phelloderm or secondary cortex. On the outer side, phellogen produces phellem or cork.
