Correct answer
C. Phellem Phellogen Phelloderm
Step-by-step solution
The cylindrical tissue that forms the protective covering of stems and roots during the early secondary growth of perennial plants is known as periderm. They are seen only in plants that show secondary growth and these tissues replace the epidermis of the same plant. Phellem or the cork is present in the outer cortical cells and prevents the rupturing of the outer tissues. Phellogen is the cork cambium and is found on the side of the phellem. Phelloderm is the secondary cortex which is produced in the inner side of
