When conquering dry land some 4x108 years ago, plants had to solve two major problems: establishing mechanical stability of the plant body, and protection from desiccation. Specific modifications of primary carbohydrate cell walls by chemically different, extracellular biopolymers represented evolutionary stable and successful solutions to both of these problems. Deposition of the aromatic biopolymer lignin to primary cell walls of carbohydrates renders
