(A) lignin
(B) suberin
(C) hemicellulose
(D) lignin​

Answer 1

Endomembrane of root thicken with Lignin.

• Lignin represent a significant part of thickened walls of plant cells and is the biopolymer is found in abundance.
• The underlying layer of a plant cell wall typically comprises the tertiary cell wall.  It is almost thick, and also lacks both in cells and the minute fibers of cellulose.
• However it is made up of both lignin and xylan, which make the compression dense and heavy.
