Heartwood is the older, central part of a tree that is dead and no longer involved in water transport. It is typically darker in color due to the accumulation of tannins, resins, and other substances.
Sap wood:
Sapwood is the younger, living wood surrounding the heartwood. It is responsible for water conduction.
C) Soft wood:
Softwood refers to the type of wood from coniferous trees. While it can have a lighter color than hardwood, both sapwood and heartwood exist in softwoods.
