As the Wood comes from trees, the Classification of Wood can be classified from the Tree types.
Classification of Trees:
Trees are classified as Endogenous and Exogenous according to the mode of growth.
Endogenous Trees: These trees grow end wards
E.g.: Palm, Bamboo

Different Types of Wood:
Generally, Wood is Classified into 3 types. They are:
1. Softwood
2. Hardwood
3. Composite/Engineered Wood
1.Softwood: The wood extracted from Conifers trees are called Softwood. Conifers are the evergreen trees having pointed leaves. They have discrete annual rings, straight fibres and are soft with pine as an exception, light in colour, resinous and lightweight.
2. Hardwood: The wood extracted from Deciduous trees are called Hardwood. Deciduous trees have flat board leaves. The annual rings are indistinct and non-resinous (generally hard), dark in colour and heavyweight.
Note: Due to their long straight trunk and better quality, Softwood is predominantly used for Construction Purposes as compared to Hardwood.
