The effect of noise on pattern formation in Turing systems is studied. It is shown how robustness of 2D patterns and 3D structures against noise depends on the characteristics of the morphology. The effect of noise is of particular interest since Turing systems are often used for explaining biological patterns or structures, which have to be stable against noise.
