Find the role of turgor pressure in sudden closing of leaves when we touch the 'touch me not' plant.

Explanation

The leaves close under various other stimuli, such a touching, warming, blowing or shaking. These type of movements have been termed seismonastic movement. The movement occurs when specific regions of cells loss turgor pressure which is the force that is applied onto the cell wall by water within the cell vacuoles and other cell contents. When the plant is disturbed, specific regions of the stems are stimulated to release chemicals including potassium ions which force water out of the cell vacuoles and the water diffuses out of the cell producing a loss of cell pressure and cell collapses.
