Question
How does cambium ring form in a dicot stem?
✓

Answer

In dicot stems, the cells of cambium present between the primary xylem and primary phloem are the intrafascicular cambium. The cells of medullary rays, adjoining this intrafascicular cambium become meristematic and form the interfascicular cambium. Interfascicular and intrafascicular cambium together form a ring of cambium called cambium ring.
