Examine the micrograph of the yeast cells. The scale bar under the photo is labeled 1 um. The scale bar works in the same way as a scale on a map, where, for example, 1 inch equals 1 mile. In this case the bar represents one thousandth of a millimeter. Using the scale bar as a basic unit, determine the diameter of the mature parent cell and the new cell. Start by measuring the scale bar and the diameter of each cell. The units you use are irrelevant, but working in millimeters is convenient. Divide each diameter by the length of the scale bar and then multiply by the scale bar's length value to give you the diameter in micrometers.arrow_forwardBiopsies from aggressive cancers often have cells that contain several nuclei per cell when viewed through a microscope.
