• B. Phellem, phelloderm, cork, secondary cortex, phellogen, periderm
• C. Phellogen, cork, periderm, secondary cortex, phellem, phelloderm
• D. Phellem, secondary cortex, periderm, cork, phellogen, phelloderm

Answer 1

The correct option is A Phellogen, cork, phellem, secondary cortex, phelloderm, periderm

Phellogen is a couple of layers thick, made of narrow, thin walled and nearly rectangular cells. It cuts derivatives on both sides. The outer cells differentiate into cork or phellem while the inner cells differentiate into secondary cortex or phelloderm. The three together is called periderm.

Thus, the correct answer is 'Phellogen, cork, phellem, secondary cortex, phelloderm, periderm.'
