Physarum Plasmodial Protrusion by Exocytosis

Electron micrograph of Physarum plasmodium extruding slime-containing vesicle onto the external agar surface. It is proposed that most of the plasma membrane required as plasmodia migrate over such surfaces is supplied by fusion of such vesicles with the plasma membrane during exocytosis.
