Close-up image of a Mimosa attached to the stem.  The Mimosa is a sensitive plant which responds to touch.  Normally the leaves of the plant are horizontal, but if one of them is lightly touched, all the leaflets drop to a vertical position.  This process is called thigmonasty.  **On Page Credit Required**
