Heartwood and Sapwood

Heartwood and sapwood are differentiated layers of wood within a tree. Heartwood is the inner layer of the tree and is the denser, darker, and older part of the tree. It is composed of dead cells and does not have a role in the transport of water and nutrients. On the other hand, sapwood is the living outer layer of the tree and is typically lighter in color. It is composed of younger, actively growing cells that can transport water and nutrients throughout the tree. Both heartwood and sapwood are important for healthy tree growth and longevity. Heartwood is often used in furniture, flooring, and other products. Its dense properties make it resistant to decay and pests, making it the preferred wood for outdoor applications. Sapwood, meanwhile, is often used in manufacturing paper, fuel, and other products. It is also a source of certain compounds and medicines.
