Cell walls architectural arrangement

Although cell wall compounds of algae and their chemical structures are mostly known to date, their interaction and spatial arrangement inside the cell wall architecture still remains challenging. 

It follows that the gain or loss of water or other liquids or vapors into or out of wood tissue can be influenced greatly by the nature, amount, and distribution of wood polysaccharides. As will be discussed in Chapter 3, these same sorption phenomena (i.e., adsorption and desorption), together with the architectural arrangement of wood cells in the tree, are responsible for particular patterns in wood swelling and shrinkage when wood is subjected to various environments. The arrangement of polysaccharide molecules within the cell wall itself, especially that of the cellulose, also has a profound effect on the physical and mechanical properties of individual cells and wood as a whole.
