Expert Answer:

Movement of leaves of touch-me-not plant is a nastic movement whereas growth of stem towards light is a tropic movement. The growth of stem is a direction based movement i.e. it grows towards the stimulus of light. However the leaves of touch-me-not fold up and droop in response to the stimulus but this does not happen in any particular direction and is not dependent on the position of the stimulus.
