Answer
The correct statement about the vascular cambium is:
It is a layer of undifferentiated cells that develops into secondary xylem and phloem.
Explanation:
- It is a type of apical meristem: This is incorrect. The vascular cambium is not an apical meristem; it is a type of lateral meristem responsible for secondary growth.
- It develops into cork cells on the outside of the cortex: This is incorrect. The vascular cambium itself does not develop into cork cells. Instead, it produces secondary xylem and phloem. Cork cells are produced by the cork cambium.
- It is a layer of undifferentiated cells that develops into secondary xylem and phloem: This is correct. The vascular cambium consists of undifferentiated cells that differentiate into secondary xylem (wood) and secondary phloem (part of the bark).
- It is located between the primary xylem and cortex: This is incorrect. The vascular cambium is located between the primary xylem and primary phloem, not the cortex. The cortex is outside the vascular cambium.
