Plants have the interesting tendency to 'find' resources in their environment. It is not uncommon to see plants whose leaves and stalks have bent over time in the direction of nearby sunlight, or plants that have grown long roots directed to a nearby source of moisture. It almost seems as if these plants are actually scanning the environment around them to find stable sources of nutrients. Since plants do not have eyes, we might ask how they are able to accomplish this. This model address the question of how a plant is able to effectively locate resources in its environment.
