Article’s title: « Les secrets de l’explosion spectaculaire du concombre du diable, le mouvement le plus rapide du monde végétal »
Response:
The explosive movement of the devil’s trumpet (also known as « concombre du diable ») is due to a rapid change in pressure within the plant’s inflated fruit. When the fruit is touched, it triggers the rupture of a thin wall inside the fruit, releasing a buildup of energy that propels the seeds at high speed. This rapid movement is considered the fastest in the plant kingdom, happening in about 50 microseconds. The mechanism behind this explosive mechanism is a remarkable example of how plants can use stored energy to ensure their seeds’ dispersal.
