- Examine the micrograph of the yeast cells. The scale bar under thephoto is labeled 1 µm. The scale bar works in the same way as ascale on a map, where, for example, 1 inch equals 1 mile. In thiscase the bar represents one thousandth of a millimeter. Using thescale bar as a basic unit, determine the diameter of the matureparent cell and the new cell. Start by measuring the scale bar andthe diameter of each cell. The units you use are irrelevant, butworking in millimeters is convenient. Divide each diameter by thelength of the scale bar and then multiply by the scale bar’s lengthvalue to give you the diameter in micrometers.Solve the crossword puzzle. - for any clue that says (2 words) you need to include a I space between the 2 words of your answer.
