Abstract

We present a mechanical study of the snapping closure of the carnivorous plant Venus flytrap (Dionaea muscipula),which exhibits one of the fastest motion in the vegetable kingdom (typically 100 ms). Using high-speed video measurements and non-invasive microscopy techniques, we propose that the fast closure of the Venus flytrap results from a snap-buckling instability, which is damped by the flow of water through the tissues. A simple model for the snapping of a poroelastic shell and experiments on the mechanical properties of the leaf tissue are completely consistent with this picture.
