Question

In a dicot stem, pericycle gives rise to

• A. Interfascicular cambium
• B. Phellogen
• C. Secondary cortex
• D. Secondary wood

Answer 1

The correct option is B Phellogen

• In dicot stem, the secondary vascular tissues originate as a result of the cambial activity.
• The cambial cells divide tangentially again and again and produce secondary tissues.
• Some of the cells of single-layered pericycle become meristematic, which divides and form a few layers of cells, phellogen.
• Hence, In a dicot stem, pericycle gives rise to Phellogen.
• So, the correct answer is 'Phellogen'.
