Question

Examine the micrograph of the yeast cells. The scale bar under the photo is labeled 1µm. 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 working in millimeters in 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.

Short answer

The diameter of the parent cell is 4µm.

The diameter of the budding cell is 3µm.

Step-by-step solution

Description of micrograph

The digital images are required to get magnified images of the microscopic cells. The micrographs help study the structural features of the cells. The micrographs are obtained from microscopes.

Diameter of the parent cell

The scale bar is given as 1 micrometer, which represents 1 unit is equal to 1 micrometer. By comparing the scale bar with the mature cell, the adult cell is four times bigger than the scale provided in the image.

The diameter of the mature cell is calculated as:

$\begin{gathered}

{\text{Diameter}} = 4 \times 1\,{\text{\mu m}} \hfill \\

{\text{ }} = 4\,{\text{\mu m}} \hfill \\

\end{gathered} $

Thus, the diameter of the parent cell is 4µm.
