Physarum polycephalum culture kit. Independent confirmation of results is a common and important practice in science. When printing this document, you may NOT modify it in any way. Introduction With a name like slime mold, it’s understandable that you would expect these organisms to be ugly and disgusting.

Four hours later, the shortest path has been selected. In all cases, the Physarum polycephalum chose the path that was the shortest between the two food sources.

If the conditions that the organism finds itself in become challenging—for example, the ground becomes dry or food becomes scarce—the plasmodium will begin to shrink and form sporangia.

Physarum polycephalum is inexpensive to obtain and it can be easily cultured on a moist surface, such as a damp piece of filter paper or an agar plate agar plates are easier to use because they stay moist. In a way, it “solved” the puzzle of finding the shortest path through the maze! A curious variation occurs when the plasmodium encounters conditions that are too severe for it to continue growing, but not severe enough to cause it to form sporangia.

Biologist Life is all around you in beauty, abundance, and complexity. Beyond basic research, biologists might also apply their research and create new biotechnology. In some countries this may not be legally possible; if so: Working with Biological Agents For health and safety reasons, science fairs regulate what kinds of biological materials can be used in amoeoid fair projects.
