Which of the following statements correctly describes the primary function and products of the vascular cambium?

  • A: It primarily produces primary xylem and primary phloem for initial plant growth.
  • B: It produces secondary xylem towards the inside and secondary phloem towards the outside, increasing stem diameter.
  • C: It forms vascular rays that transport water exclusively from xylem to phloem.
  • D: It produces bark and cork towards the outside of the stem.

Explanation

The vascular cambium is a cylindrical meristem that produces secondary xylem wood towards the inside of the stem and secondary phloem towards the outside, thereby increasing the diameter of the stem or root. It is distinct from the cork cambium, which produces cork and contributes to the bark.
