Venation structure in the wing of a Manduca sexta (from Combes & Daniel 2003).
Cell membrane contains a lipid bilayer supported by a protein scaffold (the cytoskeleton) (T. Wittmann, Science Photo Library).
Mollusk (e.g. abalone) nacre contains a chitin network that controls the growth and mechanical properties of the shell (Asaro & Harley 2004).
