Aim In this assignment I am going to carry out a practical examination on a plant (onion) and an animal (cheek) cell under a light microscope. The stain methods I am going to use are iodine for my onion cell and methylene blue for my cheek cell. Introduction All animals and plants are made up of cells. Animal and plant cells are made from millions of tiny cells‚ so small that we are unable to see them with our naked eye. Animals and plants have many features in common within a cell such

In the second part of the experiment were one drop of water was used it appeared clearer than the glass filled with water. Although Seneca’s experiment was a first step to the first microscope the use of glass and water as a form of magnification was not very effective as man could not see bacteria‚ yeast‚ blood cells or any animal swimming in drops of water from the naked eye. Around the 1600 Hans and Zacharias‚ two spectacle- markers assembled the first compound light microscope. The compound

for final‚ sharp focusing Coarse adjustment: is used initially for rough focusing Parfocal: as you cane from one objective to another you will find that your microscope is very close to a final focus Sub stage condenser: light focusing lens Iris diaphragm: used to regulate the intensity of light entering the lens system of the microscope Mechanical stage: allows total movement of the slide by turning bot knobs beneath the left side of the stage‚ one for to-and-fro‚ one for the left and right positioning

OPTICAL MICROSCOPE Introduction The optical microscope has been a standard tool in life science as well as material science for more than one and a half centuries now. The optical microscope widely use in the field of cell biology‚ microbiology‚ biotechnology‚ pharmacology‚ forensic and medical diagnosis especially when dealing with tissue fragments. It is a type of microscope which uses visible light and a system of lenses to magnify images of small samples. In other words‚ Optical microscope is a

Bairekdar Prof. Mary Flannery September 9‚ 2013 Learning parts and proper use of microscope‚ and the interception of images viewed through a light microscope Abstract: A compound light microscope uses two sets of lenses‚ ocular and objective‚ and employs light as its source of illumination. Through careful observation‚ we identified the various parts of a light microscope we found that the light microscope Ocular lenses which give 10x magnification power‚ and objective lenses

1. What type of microscope would be used in the laboratory to observe very small objects or organisms on a slide? Please give reasoning behind the answer. Which microscope would be useful when studying the internal structure of a minute specimen? (2 points) An Electron microscope‚ because they have high levels of magnification and because they can magnify the tiny details of the specimen with great clarity 2. List two jobs where microscopes are used. Describe in what capacity. (2 points)

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
