In its growing stage, Physarum polycephalum looks like a giant amoeba that spreads out like a fan, enveloping and eating everything in its path.

Template of a Physarum polycephalum labyrinth. It consumes bacteria and decaying organic matter. Keep in mind as you evaluate how many materials you will need that you will be running at least six trials of this experiment, and they can be run concurrently.

In this plasmodial stage, Physarum polycephalum orbanism a bright yellow glistening mass that can grow to more than a foot across. There are endless discoveries waiting to be found in the field of biology! In all cases, the Physarum polycephalum chose the path that was the shortest between the two food sources. Digital camera Lab notebook Disclaimer: Four hours after the setting of the agar blocks AGthe dead ends of the plasmodium shrink and the pseudopodia explore all possible connections.

Blue lines indicate the shortest paths between two agar blocks containing nutrients: Physarum polycephalum culture kit. Despite their unappealing name, slime molds are fascinating and, for some observers, beautiful organisms.

Here we show that this simple organism has the ability to find the minimum-length solution between two points in a labyrinth. Establish a culture of Physarum polycephalum and determine if it can find the shortest distance between two food sources in a maze. When the researchers placed sugar red at 2 separate points, the mold concentrated most of its mass there and left only the most efficient connection between the two points.

Our Experts won’t do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot.
