What cell structure is wood?
Rachel Acosta general

Regarding this, what kind of cells is wood made of?
Wood Cells. In softwood trees, such as pine, wood is composed of long (3 to 5 millimeters) tracheid cells that allow movement of the sap. In contrast, hardwoods, such as oak, have two kinds of wood cells: wood fibers and vessel elements.
One may also ask, what are the characteristics of wood? Wood has always been and continues to be a material of great importance to mankind. It is highly versatile. It is relatively light in weight, yet has good strength in both tension and compression; and provides rigidity, toughness and insulating properties.
