A Physicochemical Theory of Tip Growth presents the latest information on experimental observations on living organisms, including unicellular algae, hyphae and neurons. These theories are analogous to the ones developed for the growth of nonliving matter, as already exposed by the author in the book. - Presents the theory of growth and form of nonliving matter - Provides discussions on simple, unstable flat or spherical shapes which restabilize in more robust pointed shapes - Includes characteristics that are typical of the morphogenesis of living matter
