In the course of [[evolution]], leaves have adapted to different [[environment (biophysical)|environments]] in the following ways:
* [[Epicuticular wax|Waxy]] micro- and nanostructures on the surface reduce wetting by rain and adhesion of contamination (''See [[Lotus effect]]'').
* [[Epicuticular wax|Waxy]] micro- and nanostructures on the surface reduce wetting by rain and adhesion of contamination (''See [[Lotus effect]]'').
* Divided and compound leaves reduce wind resistance and promote cooling.
