What is Wood?

Wood are derived from the stem, trunks and branches of trees.

A wood is an organic material and a structural tissue composed mainly of cellulose; and it constitutes the stem, roots and branches of trees.

You can read on the Trees found in the Tropical Rainforest here.

The outermost skin or covering of the wood is called the bark. On peeling off the bark, next to be seen is the sapwood which contains the plant's transport system called the xylem. Also seen inside the sapwood is the heartwood, but here, the xylem is blocked with gums; making it functionally inactive. The cambium is seen around the edge of the sapwood.

We have two types of wood. They are

  1. Hardwood
  2. Softwood

Note: Woods are porous and fibrous and the terms 'hardwood and softwood' don't always refer to the wood's actual hardness or softness.

Hardwood - Len Academy

Hardwoods are derived from angiosperms.

Angiosperms are flowering plants that produce seeds encased in fruits or pods.

Please read on the Reproductive Differences between Gymnosperms and Angiosperms.

Most times, hardwood are stronger than softwood but there are exceptions. For instance, balsa is a hardwood that is actually soft.

Characteristics of Hardwood

  1. They usually have a higher density than softwood. Balsa is an exception.
  2. They are usually more expensive than softwood.
  3. They grow at a slower rate than softwood.
  4. Hardwood trees shed their leaves in certain times of the year.
    You can read on the Differences between Plants and Crops here.
  5. Hardwood are more fire resistant than softwood.
  6. The leaves of hardwood trees are evergreen.
  7. They are used for making quality furniture (in terms of strength). They are also suitable for decking in buildings.
  8. Hardwood trees always have divided trunks which are sometimes referred to as a dendritic form.
  9. In terms of price, hardwood are usually more expensive than softwood.
    You can read on Scale of Preference and Opportunity Cost here.

Examples of hardwood include iroko, ash, beech, alder, teak, birch, mahogany, maple, oak, balsa and walnut.

Softwoods are often derived from coniferous trees; that is, trees with needle-like leaves and whose seeds are covered in cones.

Note: Coniferous trees are classified under gymnosperms.

Please read on the Anatomical and Structural Differences between Gymnosperms and Angiosperms here.

Characteristics of Softwood

  1. Most softwood have a lower density than hardwood (weighs lower).
    Please read more on Density here.
  2. In terms of price, they are often less expensive than hardwood.
  3. Their growth rate is faster than hardwood.
  4. Most do not shed their needle-like leaves during the year. The softwood larch and cypress are exceptions.
  5. Please read on the Characteristics of Ceramics here.

  6. They are less fire resistant.
  7. Their leaves are evergreen, just like hardwood.
  8. You can read on Interesting Facts for Students here.

  9. Softwood serve various purposes; For instance many doors, windows and papers are made from softwood.
  10. They normally have a single dominant trunk referred to as excurrent form.
  11. Softwood trees are usually tall and straight.
  12. Most are cheaper than hardwood.

Examples of softwood include cedar, larch, juniper, yew, cypress, fir, pine, spruce, douglas fir and redwood.
