Collenchyma cells are unique in their structure and function. Which of the following best describes a distinctive feature of collenchyma cells?

  • A: They possess uniformly thickened primary walls for general support.
  • B: They are typically found in older, woody parts of the plant, providing rigid support.
  • C: They are living cells at maturity and provide flexible support to young plant shoots.
  • D: Their secondary walls contain large amounts of lignin, making them highly resistant to elongation.

Explanation

Collenchyma cells are living at maturity and provide flexible support to young, growing plant parts. A key distinguishing feature is their unevenly thickened primary walls.
