(D) The movement of leaves in $Mimosa$ $pudica$ (touch-me-not plant) upon stimulation is a type of thigmonasty (seismonasty).This movement is caused by the loss of turgor pressure in the specialized cells located at the base of the leaflets and leaves,known as the pulvinus and pulvinules.When touched,the cells in the pulvinus lose water to the intercellular spaces,leading to a decrease in turgor pressure,which causes the leaves to droop.Therefore,all the mentioned factors contribute to this phenomenon.
