Summary
Biological locomotion for both major classes of organisms, prokaryotes and eukaryotes, is three-dimensional and is dominated by the presence of slender filaments, flagella, which are rotating and waving in viscous fluids. In this fifth chapter, we return to the biological movements seen in Chapter 1 and consider the relationship between the cellular shapes and their motion. Using elementary concepts from Stokes flows, we propose an intuitive physical and mathematical interpretation for the generation of propulsive forces by moving flagella and for the natural occurrence of helices and waves in cellular propulsion.
