Giraffes have a compensatory precision in their movements, so that although it takes longer for them to respond to stimuli, they might do it more accuracy. The move fiber in a given nerve, the more fine-tunes a response to stimuli.
In plant seeds, the photoreceptor phytochrome is responsible for the process termed photomorphogenesis<span>. This occurs when a seed initially situated in an environment of complete darkness is exposed to light. A brief exposure to electromagnetic radiation, particularly that whose wavelength is within the red and far-red lights, results in the activation of the photorecepter phytochrome within the seed. This in turn sends a signal through the signal transduction pathway into the nucleus, and triggers hundreds of genes responsible for growth and development</span>
