Cell culture molecular biology primarily involves cultures of cells on flat plastic dishes. This technique is known as two-dimensional (2D) cell culture, and was first developed by Wilhelm Roux who, in 1885, removed a portion of the medullary plate of an embryonic chicken and maintained it in warm saline for several days on a flat glass plate. From the advance of polymer technology arose today's standard plastic dish for 2D cell culture, commonly known as the Petri dish. Julius Richard Petri, a German bacteriologist, is generally credited with this invention while working as an assistant to Robert Koch. Various researchers today also
The Dish service a backup generator, putting their part in the mission at risk. They apply all their science skills to reacquire the signal and cover their mistake, so that everything works out in the end. The directors of the film portray, quite accurately, what is in essence, a complex technical task, such as re-pointing the dish when it loses the signal's "lock" and deciding to use it when the wind whips up threatening to damage the structure. The film dramatises the team-work of a few technicians, who sometimes nearly lose their tempers with each other, painted against a backdrop of proud
