They fold up upon touch- to prevent being eaten, and in the presence of fire- to limit the damage.

Well, droopy leaves are a lot less attractive to herbivores than big lush leaves on other plants. The plant also responds to this when there is a lack of water, because the curling gives a smaller surface area for water loss by transpiration.

I guess is not one thing but a sum different benefits, like you propose, Perhaps catterpilars and other like creatures will be descorage eventhou it those not seem as efective as been poisonus or untastefull. Still a bit unclear since there are not that many plants that show this same activity.
How those the stimulus is trasfer to the cells that react? is it mecanichal?

It is a variation in osmotic pressure that makes the leavs behave like that
