Answer 2

Hi there :)

⬇ Formation of cork ⬇

☇As plants grow old, cork is formed from a secondary lateral meristem called phellogen or cork cambium.
☇It develops subepidermally in older stems and roots.
☇Cells cut out on the outer side by cork cambium form cork or phellem while cell out on the inner side give rise to secondary cortext or phelloderm.
☇The whole tissue (cork, cork cambium and secondary cortex) is called periderm.

Hope it helps ^_^
