General Biology 1201 Lab #2 Post LabRaphael SevillaSeptember 25, 20141. Describe how a microscope helps to view specimens that are too small to be seen with the naked eyesa. A microscope helps to view specimens that are too small using a system of lenses to produce an enlarged, focused image of a specimen, making it easier to see the specimen. 2. Name four important parts of a microscope, and describe the function(s) for eacha. Four important parts of a microscope include the light source, the condenser lens, the ocular, and the stage. The light source is a light bulb located at the base of the microscope. The condenser lens focuses light from the light source onto the specimen. The ocular is the lens the person looks through to see the specimen. The stage holds the specimen to be seen. 3. Why must specimens viewed with a compound microscope be thin? Why are they sometimes stained with dyes?a. Specimens viewed with a compound microscope must be thin because since the distance between the stage and the objectives isnt as much as the dissecting microscope, you do not want to damage the specimen. Sometimes specimens are stained with dyes so they are easily seen.4. Examine the micrograph of the letter e shown in figure 3.4. This letter is magnified 40X. What is the actual height of the letter?a. 97 cm.5. As a General Biology student, you have been given access to a stage micrometer, an ocular micrometer, a compound microscope, an onion, and necessary supplies, and you are asked to measure the size of the onion skin cell. Please describe the procedures and how you will do the calculation. a. In order to find the size of the onion skill cell. First I would determine the size of the field of view, so first I would count how many spaces on the stage micrometer fit precisely in a given number of spaces on the ocular micrometer. Since I know that the smallest space on a stage micrometer is equal to .01 micrometers, I would calculate how many micrometers are in 1 ocular space, then examining the specimen, using a compound microscope, I would see how many spaces the onion skin cell would take up, then I would multiply that number by the predetermined number of micrometers in one ocular space
