Timber Tree any tree that produces wooden of commercial importance. Wood is a material of plant origin characterised by fibrous shape and composed largely of lignin and cellulose. The high lignin content 25% contributes unique tension to the structure and thus distinguishes wood from other plant materials.
Woods are labeled in two groups: softwood and hard wood. Softwood is derived from the gymnospermous mainly coniferous plants and hardwood is derived from angiospermous mainly dicotyledonous plants. |
