What is the character of touch me not plant?
The leaves fold as a result of the internal movement of water, and the mechanics of the process are now well-documented. A stimulus, such as touch or air movement, triggers certain areas of the stem to release chemicals, which cause water to move out of cell vacuoles and leads to cell collapse.The sensitive plant is popular in cultivation around the world, and is enjoyed by many as a curiosity due to its highly touch-sensitive leaves.

This rapid plant movement is thought to act as a defence against herbivores, which may be deterred by the dramatic response, or if they are small, may be dislodged as the leaves collapse.
