Critical Care Medicine ... One landmark in the long history of biological studies on the "slime mold" Physarum polycephalum was the introduction of chemi­ cally defined growth conditions for the plasmodial phase of this organism in the laboratory of Harold P. Rusch in Wisconsin in the 1950s. Physarum polycephalum is a plasmodial slime mould. The slime mold Physarum polycephalum is an especially useful organism for these studies because of its large size and its suitability for both physiological and biochemical in- vestigations. The plasmodiam is the active feeding stage of the organism. These massive cells can live in cool, damp areas in temperate forests, and are able to stretch out with slimy tendrils to search for prey, which includes bacteria, fungi, … Below are some ideas for student investigations, followed by background information on the organism.

The ethanol-resin mixture was care-fully removed and the last step was infiltration of the tissue witha pureglycidether(A+ B) mixture for a total of45min,). With a little care and attention, Physarum polycephalum is easy to grow in the classroom and is a good organism for students to use for independent investigation. If the plasmodium dries during feeding it forms a crusted resting stage known as the sclerotium. Take slime mold. Then the plasmodium emerges and continues to feed.
