Microscopy

  1. 1. Microscopy and Photomicrography During the workshop on microscopy and photomicrography, given to us by Dr. Ross, wewere able to learn about several techniques that are implemented in different areas ofbiological research (i.e. microbiology, cell biology, botany, etc.). We learned that there are twotypes of microscopes used for microscopy: (1) the electron microscope (2) and the lightmicroscope. The difference being that one-the light microscope-uses visible light in order todetect small objects, and the other-electron microscope-uses an electron beam, that has nowavelength, to illuminate the specimen. With light microscopy there are a few techniques thatcan be applied in order to improve the visible quality of the specimen such as: themicrotechnique, whole mount, cross sections, bright field, dark field, and phase contrast. Inorder to practice these techniques we were assigned different specimens to observe. I wasassigned the aphid, which is a small parasite like insect that leeches off of plant nutrients. Toobserve the aphid I used the dissecting microscope at a 5.6x10 magnification.
