TLDR
In this paper, the moduli and crushing strength of balsa wood were determined by the properties of the cell-wall material, and, in part, by the dimensions and shape of the cells themselves.Abstract:
The structure of balsa wood has been characterized by scanning microscopy. The moduli and crushing strengths of the wood, in three orthogonal directions, have been related to the structure and its response to load: during deformation the cell walls bend elastically and collapse plastically or by fracture. It is found that the moduli, crushing strengths and anisotropy of balsa and of other wood are determined, in part, by the properties of the cell-wall material, and, in part, by the dimensions and shape of the cells themselves. This second aspect of the deformation determines how moduli and strength depend on the density of the wood, and is treated here for the first time.read more

The hierarchical structure and mechanics of plant materials
TL;DR: This study reviews the composition and microstructure of the cell wall as well as the cellular structure in three plant materials (wood, parenchyma and arborescent palm stems) to explain the wide range in mechanical properties in plants aswell as their remarkable mechanical efficiency.
