When we touch the leaf of a sensitive plant, also known as the touch-me-not plant, its leaves close, shrink and go to sleep.

Although it does not have a nervous system, its leaves, when touched, release certain chemicals like potassium ions within the plant's body.

The chemicals produce water and cause the electrolytes to flow out of its cells.

This leads to loss of cell pressure, due to which cells collapse and the plant squeezes its leaves to shut.

In some cases, neighboring leaves also close becuase of the chemical getting transmitted during the process.
