Question

Describe the change that occurs in a touch-me-not plant when it is touched?

Answer 1

If we touch the touch-me-not plant at one point, all the leaflets show the folding movement. This indicates that the stimulus at one point is communicated. The folding effect of touch-me-not plant is caused by a change in the turgidity of the leaflets brought about by the movement of water into and out of the parenchymatous cells of the pulvinus or swollen leaf base.
