1. The wood needed for the construction of buildings and making of furniture are obtained from certain plants.
2. We use wood for these purposes due to their features like durability, stylish finishing and resistance to temperature changes.
3. All commercial timbers are classified into two classes as Hardwoods and softwoods based essentially on their structure.
i. Hardwoods:
Hardwoods are angiosperms (flowering plants), the largest group of land plants. High-quality furniture, decks, flooring and wooden construction are being made only using hardwood.
Example: Teak, Jackffuit.
ii. Softwoods:
Softwoods come from gymnosperm (nonflowering plants) trees. Certain angiosperms also yield softwood.
Softwoods have a wide range of applications such as making plywood, wooden boxes, medium-density Fibreboard (MDF) and paper making.
Example: Katampu, Pine.
