And God said, Let the earth bring forth .... tree yielding fruit after his kind, whose seed is in itself, upon the earth: and it was so.
Genesis 1:11
"Lignin is the molecule that gives sturdiness to cell walls and is a major component of wood.
--Its presence differentiates land plants from the slimy algae of the waters.
“Because lignins are very complex natural polymers with many random couplings, the exact chemical structure is not known,” states The Lignin Institute."
