Based on the provided diagram and text, which of the following accurately represents the primary components of a plant's bark?

  • A: Vascular cambium and secondary xylem.
  • B: Heartwood and sapwood.
  • C: Secondary phloem, cork cambium, and cork cells.
  • D: Primary xylem and primary phloem.

Explanation

The text states that the periderm consists of 'the cork cambium plus the layers of cork cells it produces.' The diagram explicitly labels 'Bark' as encompassing 'Layers of periderm' and 'Secondary phloem.' Therefore, the bark is composed of secondary phloem, cork cambium, and cork cells.
