Plant pollen are cells which exhibit a plethora of surface patterns, including stripes, hexagons, foam-like ridges, and arrangements of spikes. The spherical shape of the cells ensures that these various patterns have defects. We study the development of these patterns and conjecture that the diversity of the observed patterns, and their reproducibility within a single species, may be explained by a first-order phase transition from an unpatterned to a patterned state.
