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

1. Just outside the vascular cambium
2. Just inside the vascular cambium
3. Just inside the vascular primary phloem
4. Just outside the secondary xylem

Correct answer: Just outside the secondary xylem

Solution

The vascular cambium produces secondary xylem toward the inside and secondary phloem toward the outside. As more xylem is added inward, the oldest secondary phloem ends up nearest the secondary xylem, just outside it.
