- During a microscopy exercise in the anatomy laboratory,a student makes the following observations about a tissuesection: (1) The section contains some different types ofscattered protein fibers—that is, they exhibit differentwidths, some are branched, some are long and unbranched,and their staining characteristics differ (some are seenonly with specific stains). (2) Several cell types withdifferent morphologies are scattered throughout the section,but these cells are not grouped tightly together. (3) Theexamined section has some “open spaces”—that is, placesbetween cells and the observed fibers in the section thatappear clear with no recognizable features. What type oftissue is the student observing?

- Why does a muscle cell contain many mitochondria, and why does a white blood cell contain many lysosomes?-Mature parent cell Budding- cell 1 μη Test II. 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.Define cell junction
