Leaves of the sensitive plant protect themselves from predators and environmental conditions by folding in response to touch.

BIOMIMICRY TAXONOMY
Summary
"When the leaf is touched, it quickly folds its leaflets and pinnae and droops downward at the petiole attachment…The leaves also droop at night, and when exposed to rain or excessive heat. This response may be defenses against herbivorous insects, leaching loss of nutrients, or desiccation. The folds of different leaves are interconnected and compatible with each other, and the whole structure can be folded and unfolded from a single or multiple driving points." (Patil 2007: 19-23)
