Reply	Jason says: The plant you are referring to is called a "Sensitive Plant". The wilting is a defense mechanism presumably against wind damage/dehydration. The botanical name for this plant is Mimosa piduca. It is a good model for botanists to study Na+ transport in cells since the mechanism is based upon the movement of ions across the membranes of cells found in the petioles.  (no votes) Tags: unanswered, domestic science, plants.

Reply	Adam H says: We have several varieties of mimosa in Thailand that wilt when touched or disturbed (some of them more dramatically than others).I had been told that it was a defense against being eaten and certainly if you walk into a lush looking clump of them they quickly change their appearance and look very dead and dried up.  (no votes) Tags: unanswered, domestic science, plants.

Reply	Anonymous says: Those are amazing videos!By the way, don't plant mimosa in your yard, if you live in the northeast of the U.S. It grows and spreads like a weed, is soft-wooded, and is very difficult to dig up or kill.  (no votes) Tags: unanswered, domestic science, plants.
