magnification that can be achieved by an electron microscope. * explain the need for staining samples for use in electron microscopy Lesson 2 * calculate linear magnification of an image such as photomicrograph or electron micrograph Key words * Resolution= the ability to distinguish 2 separate points as distinct from each other. * Magnification= the number of times greater an image is than the actual object itself. Light microscopes have a low resolution‚ therefore if the magnification

The microscope has been one of the greatest inventions in the history of science and has had the most impact on the course of science. Ever since the first microscope was invented in 1590‚ they have improved our knowledge in basic biology and biomedical research‚ as well as many other things‚ all of which are important. The smallest object a human can see with the naked eye is 0.2 mm‚ for example‚ algae cells. The light microscope‚ however‚ allows us to see things almost 1000 times smaller that what

experiment is to learn how to use a microscope while viewing various types of bacteria cultures. Prepared slides are used to view bacterial cultures under a microscope that would normally be invisible to the naked eye. Bacterial shapes and arrangements or morphology are observed in prepared slides and fresh yogurt culture. Purpose: The experiment is meant to determine the shapes of bacteria under different magnifications when using a microscope; 10X‚ 40X‚ and 100X. A microscope must be used to see and study

Page 1 INTRODUCTION The purpose of lab 1 was to learn about general bacteria’s and the use of a compound microscope. The microscope contains biconvex lenses‚ bi- meaning two. The basic frame of the micro scope consists of a base‚ a stage to hold the slide‚ an arm for easy carrying‚ and a body tube for transmitting the magnified image. The light source is in the base. One can focus on the image of an object by moving the lens closer to the slide or the stage closer to the objective lens‚ using
