Volatile compounds found in oregano destroy fungi by breaking down their cell membranes.

Wings of penguins reduce heat loss by forming a countercurrent heat exchanger via the vascular design.

Tree canopies avoid wind damage by changing shape to become more aerodynamic.

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