Microscope_Cell_Lab report Microscope and the Cell Lab Report Name, date, course and section required for password: Mayling Alvarez, 5-22-19, BIOL-1408,74426 I. Purpose of the Microscope 1. Define contrast. , 2. Microscopes magnify the image of a specimen. How is this accomplished? 3. Describe the correct way to handle a microscope. G II. Compound Microscope 1. Describe the location and function of the following parts of the microscope: a. stage clips – b. eye piece – c. condenser – d. objective lenses – 2. Define total magnification. III. Viewing Microscope Slides 1. Using at least five steps, describe how to focus a microscope in order to view the cells of a petal on low magnification. 2. Go to lab, Section III, Exercise 4 to study specimen orientation and answer the following questions: a. With the scanning lens in place, the prepared slide is moved to the right. In which direction does the image appear to move? b. The slide is moved away from you. In which direction does the image move? IV. Depth of Field 1. What diaphragm adjustment should be made to more easily determine the order of the colored threads? 2. Explain how depth of field can be used to reconstruct structure. V. Microscopic Measurement 1. Go to lab, Section V, Exercise 6 to discover how to measure the diameter of the field of view. a. What is the diameter of the field of view under scanning power (40X) in micrometers (µm)? b. What is the diameter of the field of view under low power (100X) using the following equation: Diameter of field of view of 100X (µm) = (4400µm) x (40X) = µm 100X VI.
