Question

In root, pericycle gives rise to

• A. Branch roots and cork cambium
• B. Cortex and pith
• C. Epidermis and vascular bundles
• D. Xylem and phloem

Answer 1

The correct option is A Branch roots and cork cambium

Pericycle is the parenchymal layer inside endodermis. It gives rise to lateral or branch roots. For secondary growth in plants, the pericycle contributes to the vascular cambium often diverging into a cork cambium.

In dicot stems, the pericycle strengthens the stem and provides protection for the vascular bundles.

In dicot roots, the vascular cambium is completely secondary in origin, and it originates from a portion of pericycle tissue.
