Use a pin to carefully lower the cover slip over the slide‚ ensure there are no air bubbles before the use of the slide. Set the microscope to its lowest power objective lens (x4) and make sure it is in line with the optical tube‚ also that the microscope light is turned on. After preparation of the slide and microscope‚ carefully place the slide onto the microscope stand. Looking from eye-level of the stand‚ lower the tube using the coarse focus know until the end of the objective lens is just

A) to the fluorescent microscope. Count the number of elementary bodies you see through the microscope (recall that elementary bodies stain green)‚ enter the number of elementary bodies in the field below‚ and then click Submit Data to display your results in the grid. After you click Submit Data‚ the slide will automatically be placed in the biohazardous waste disposal. You answered: 0 elementary bodies 16. Drag the next slide (patient B) to the fluorescent microscope. Count the number of

ability to distinguish between two separate points. * An increase in magnification does NOT necessarily mean an improvement in resolution. Ex. A light microscope has a max resolution of 200nm meaning that if two points are closer than 200nm they can’t be distinguished as separate no matter how large the magnification. The electron microscope When a metal becomes very hot‚ some of its electrons gain so much energy that they escape from their orbits. They behave like electromagnetic radiation

organisms’ basic units of structure and function‚ and cells only come from existing cells. Their discoveries lead to the development of inventions necessary to induce further research in the area which resulted in the creation of devices such as the microscope. Robert Hooke Robert Hooke was probably the greatest experimental scientist of the seventeenth century. He was able to observe cells through studying thin slices of cork which was probably one of his most famous discoveries. He discovered plant
