3.1 How Cells are Studied1. A microscope is an instrument that magnifies an object.2. Images of cells taken with a microscope are called micrographs.Light Microscopes1. Click on figure 3.2 and study the image of the two kinds of student light microscopes.1. Name the two student lab microscopes shown in the image.1. A light microscope may magnify an image up to approximately 400-1000 times.2. Define the two parameters that are important in microscopy.1. Magnification - The degree to which the image of an object is enlarged.2. Resolving Power - The ability to distinguish two adjacent structures as separate.Electron Microscopes1. How do electron microscopes differ from light microscopes?Cell Theory1. List the three principles of the unified cell theory.2. All living organisms are composed of one or more cells.3. The cell is the basic unit of life.4. All cells arise from pre-existing cells. 3.2 Comparing Prokaryotic and Eukaryotic CellsComponents of Prokaryotic Cells1.
