It would a hell of a lot easier to see what you are wittering about
if you didn't both top post and leave the previous posting unedited.
Please do not be so lazy and inconsiderate.

Wilting is (largely) a loss of turgidity due to the water
evaporating - i.e. a direct effect. Mimosa pudica's response to
touch necessarily involves a more complex mechanism; in particular,
the response is not entirely local, which implies some degree of
communication. And nerves are nothing more than communication
links.

A far better analogy is the mechanism used for water transport
between the roots and leaves of a tree. No nervous system is
involved, but it is NOT as simple a mechanism as simple wilting.
