Question

The waxy material located on the cork cell wall is called

• A. Suberin
• B. Lignin
• C. Cutin
• D. Hemicellulose

Answer 1

Answer:

A. Suberin

• After the leaf falls, the scar is exposed to air, forming a first protective layer on the scar's wall through the deposition of lignin and suberin.

• Suberin is a waxy chemical found in the thicker cell walls of many trees and plants, notably in cork tissues, and is comparable to cutin.

• The outer cork cambium eventually loses protoplast and dies, resulting in the suberization of the cell walls.

• Suberin deposition (suberization) creates a water-resistant layer.
