09Why are phenols "biochemical" but cork "structural"?
Ask what the defenceis: a physical object or barrier (cork, wax, tyloses, gum plug, thick wall) is structural; a substance that poisons or neutralises a pathogen (phenols, glycosides, canavanine, detoxifying enzymes) is biochemical.
Gum is a borderline case, but the book classes it as structural because it acts as a physical seal.
