According to Concept 35.4, what is the primary role of the vascular cambium during secondary growth in woody plants?

  • A: Producing new root cap cells to protect the root tip.
  • B: Generating alternating internodes and leaf-bearing nodes along the shoot.
  • C: Producing secondary xylem and secondary phloem, leading to an increase in stem diameter.
  • D: Forming stomata and regulating gaseous exchange in leaves.

Explanation

Concept 35.4 explicitly states: 'The vascular cambium is a meristematic cylinder that produces secondary xylem and secondary phloem during secondary growth.' This process increases the diameter of stems and roots.
