A biophysical model based on the poro-elastic properties of the cells of the filamentous brown alga Ectocarpus is described, which allows to simulate cell shape changes and subsequent filament branching during the algal growth. This shows that mechanical factors only can account for the major developmental processes as observed in vivo in this organism.
