Fibers that are used in textile manufacturing come from cotton, flax, and hemp plants. The wood from timber production is used to make furniture, homes and many other products. Many chemicals such as acetic acid, methanol, and turpentine are obtained from trees.

Plants most important Roles n Medicinal uses n n Scientists continue to study many different types of plants to try and understand the various chemical compounds found within them.
