Abstract

This article considers the underpinning role of interactive forces at the cell wall and cellulose–fibre interfaces in the physiological and biophysical functionality of the various non-cellulosic components that are present within the plant cell walls. We specifically introduce the use of tribological science (friction and lubrication) to obtain new insights into relative movements occurring between cells and between cellulose fibrils within the cell walls, and the potential influence on friction forces by pectin, hemicelluloses, and expansins. This approach may provide a basis for describing physical phenomena which define the system's behaviour during growth, morphogenesis, and mechanical deformation of plants.
