Initiation of lateral roots and vascular cambium during the secondary growth takes place in
Open in App
Solution
The correct option is B Pericycle
Secondary growth is an increase in the thickness of the shoots and roots of a vascular plant as a result of the activity of the two lateral meristems, the cork cambium and vascular cambium.The pericycle is a cylinder of cells that lies just inside the endodermis and phloem in plant roots while in stems, it is situated around the ring of vascular bundles. It has the capacity to regulate the formation of lateral roots by rapidly dividing near the xylem elements of the root. It strengthens the roots and provides protection for the vascular bundles.In plants undergoing secondary growth, the pericycle contributes to the vascular cambium often diverging into a cork cambium.So, the answer is D.
