Lignin is a complex polysaccharide (therefore a carbohydrate).

There are no amino acids, nitrogenous bases, or fatty acids-- therefore lignin must be a carbohydrate and have sexy glycosidic linkages.
Wikipedia says it so it must be true.

Lignin would fall into the functional group OH.
lignin hardened vascular tissues to transport water and nutrients
Lignin is a type of polymer found in the cell walls of plant cells that provides support and structure for the plant- it makes them rigid.

Acidified phloroglucinol is used as a stain for the detection of lignin. If lignin is present, it will turn a bright red colour.

One of the things that phyloroglucin contains is lignin.
The source of lignin in the soil is dead plants.
Lignin is a biopolymer that gives support to vascular plants, and is thought to have evolved after aquatic plants took on land. many aquatic plants produce lignin or lignin-like polyphenols however. There is still debate on distinguishing terrestrial from aquatic plant lignin.

A chemical substance called lignin hardens cell walls. Lignin is formed by removing water from sugars to create aromatic structures.
