Wood

Wood is generally used to describe the solid or hard tissue of the stems (trunk, branches and twigs) of trees and shrubs. Botanically, wood is defined as the secondary xylem of seed plants produced by cambium. According to this definition, however, the woody tissues of palm trees and other higher plants are not wood in the narrower sense. However, the storage of lignin in the cell wall is also characteristic here. In a broader definition, wood is therefore also understood as lignified plant tissue. From a cultural-historical point of view, woody plants are probably among the oldest used plants. As a versatile, but especially renewable raw material, wood remains one of the most important plant products to this day.
