Light micrograph of a monolayer of cells from an onion Allium cepa, showing the elongated shape of the individual cells. The cell walls, which appear as dark outlines, are wedged close to each other in neat order. This microscope slide was made as an example of a normal preparation technique for use under a light microscope. It compares with B060/050 through B060/053, which were made to show poor techniques, such as the inclusion of air bubbles on the slide or folded layers of tissue that obscure details of the cells. Magnification: x100 at 8x10 inch size.
