Figure 5. — Spatial profile of mechanical properties and biochemical processes in the cell wall of growing pollen tubes. Reproduced from [110]. Mechanical modelling has shown that the precise spatial distribution of endomembrane trafficking, cell wall assembly processes and cross-linking of cell wall polymers determines the cellular morphogenesis and the resulting shape in growing plant cells. Rboh transfers electron from NADPH to O₂ to form . The charge produced across the plasma membrane must be compensated by the influx of anions, like Cl⁻, or the efflux of cations. Protons can also be exchanged for cations such as Na⁺ or K⁺. The influx of osmotically active ions would increase turgor and power tip growth.
