Question

Choose correct option w.r.t. origin of cork cambium in dicot.

• A. Completely primary in both
• B. Completely secondary in both
• C. Partly primary and partly secondary in both
• D. Primary in stem and secondary in root

Answer 1

The correct option is B Completely secondary in both

The vascular cambium and cork cambium are secondary meristems that are formed in stems and roots after the tissues of the primary plant body have differentiated. The vascular cambium is responsible for increasing the diameter of stems and roots and for forming woody tissue. The cork cambium produces some of the bark. Hence, the origin of cork cambium in dicot is completely secondary in both.
