Question

After the secondary growth, the youngest layer of secondary phloem in a dicot stem is located

• A. Just outside the vascular cambium
• B. Just inside the vascular cambium
• C. Just inside the primary phloem
• D. Just outside the secondary xylem

Answer 1

The correct option is A Just outside the vascular cambium

In dicot stem, during secondary growth, primary xylem is pushed towards the centre while primary phloem is pushed outside the cambium and is finally crushed due to internal pressure after the secondary growth.

Thus, the correct answer is option A.
