How do plants move?

Most plants do not move much, but move when growing, but it is a very slow process. Others have the ability to make quick movements. For example, the carnivorous plant Dionaea muscipula in the photo closes the leaves if you notice food. On the other hand, the fruit of the plant Ecballium elaterium explodes to distribute the seeds and the small flowers of the Cornus canadensis or Canadian Zuhandor throw into the sky.
A group of botanists, including researcher Mahadevan, analyzes the movement of plants. There seem to be three ways to move. To make small, slow movements, the cells inflate and empty. The leaves of the Dionaea muscipula plant, on the other hand, are able to store energy, which is then used when they need it. Finally, the Canadian tuft bases movement on intracellular pressure: the pressure increases to the point where the cell explodes.
According to the researchers, the key is in the speed of fluid arrival in the tissues, which differentiates the three types of movement. In addition, they have shown that fungi use the same system to move.
