AXylem vessels, mature and lignified
BApical meristem of a shoot tip
CCambium ring inside a tree stem
DLateral meristem in a young root
Answer & Solution
Correct answer: A. Xylem vessels, mature and lignified
1. Meristems retain the ability to divide; they are not permanent.
2. Cells that lose this ability take on a specialised role as permanent tissue.
3. Xylem vessels stop dividing once mature.
4. So xylem is a permanent tissue.
