Question

Periderm is produced by

• A. Vascular cambium
• B. Fascicular cambium
• C. Phellogen
• D. Intrafascicular cambium

Answer 1

The correct option is C Phellogen

A. Vascular cambium – produce secondary vascular tissues and ray parenchyma.

B. Fascicular cambium – a strip of cambium present between the xylem and phloem of a vascular bundle is called fascicular cambium. It involves in the secondary growth.

C. Phellogen – a ring of cambium formed in the cortex of dicot stem, by the dedifferentiation of parenchyma is called Phellogen. It is involved in the formation of periderm.

D. Intrafascicular cambium - a strip of cambium present between the xylem and phloem of a vascular bundle is called fascicular cambium. It involves in the secondary growth.

So, the correct option is ‘phellogen’.
