An element is a pure substance that cannot be further subdivided into purer or simpler forms. A compound is made up of two or more different elements and can thus be divided into simpler forms (individual elements).  A compound contains these elements in a fixed ratio and has properties that are different from each constituent element. A mixture is made up of different elements or compounds, where each constituent retains its original properties. A mixture can also be separated into individual constituent by physical means. Wood is composed on a number of compounds, including water, cellulose, lignin and hemicellulose. The relative concentration of each of these varies from plant to plant. All these compounds are in turn made up of elements, such as carbon, hydrogen and oxygen. In essence, wood is a heterogeneous mixture.

Hope this helps.
