Wood anatomy is a scientific sub-area of wood science, [1] which examines the variations in xylem anatomical characteristics across trees, shrubs, and herbaceous species to explore inquiries related to plant function, growth, and the environment.
Coniferous tree sap is a viscous liquid that contains terpene, a volatile hydrocarbon. Over time the evaporation of the terpene changes the state of the sap; it slowly gets thicker until it hardens into resin. New fatwood leaks the sticky sap, while in aged fatwood the sap has hardened and is no longer sticky.

Alpha-pinene is the most widely encountered terpenoid in nature [6] and is highly repellent to insects. [7]Alpha-pinene appears in conifers and numerous other plants. [8] Pinene is a major component of the essential oils of Sideritis spp. (ironwort) [9] and Salvia spp. (sage). [10]
Pine tar is a form of wood tar produced by the high temperature carbonization of pine wood in anoxic conditions (dry distillation or destructive distillation). The wood is rapidly decomposed by applying heat and pressure in a closed container; the primary resulting products are charcoal and pine tar .
