Hormones are not transported in vesicles, instead they mix in the blood and then get transported throughout the body. 

A rapid and temporary plant movement in response to the stimulus of touch is known as seismonastic movement. 

Folding of leaves because of seismonasty protects the mimosa plant from being eaten by herbivores. In the folded leaves, there is less exchange of heat as compared to fully expanded leaves. This offers higher survival value under environmental stress.
