Wood is a natural material made up of cellulose fibers, which are found in plants and trees. There are many different types of wood, each with its own unique characteristics. Some common types of wood include pine, oak, cherry, walnut, mahogany, birch, poplar, and maple. Each type of wood has its own set of properties, such as strength, durability, hardness, and density. Different types of wood also have different uses, ranging from furniture to construction materials.
