<P> Rapid plant movement encompasses movement in plant structures occurring over a very short period , usually under one second . For example , the Venus flytrap closes its trap in about 100 milliseconds . The dogwood bunchberry 's flower opens its petals and fires pollen in less than 0.5 milliseconds . The record is currently held by the white mulberry tree , with flower movement taking 25 microseconds , as pollen is catapulted from the stamens at velocities in excess of half the speed of sound -- near the theoretical physical limits for movements in plants . </P>
