A microscopy lab report is a document that describes the results of a microscopy experiment. In biology, microscopy is a technique that uses a microscope to observe and analyze small structures or organisms that are not visible to the naked eye. These structures can include cells, tissues, and even subcellular components such as organelles.

There are several different types of microscopes that can be used in a biology lab, each with its own strengths and limitations. The most common types of microscopes used in biology are light microscopes, electron microscopes, and fluorescence microscopes.

Light microscopes use visible light to magnify and illuminate the specimen, and are the most commonly used type of microscope in biology labs. They can be further divided into several subtypes, including compound microscopes, which use lenses to magnify the specimen, and stereo microscopes, which use two separate optical paths to produce a three-dimensional image.

Electron microscopes use a beam of electrons instead of light to magnify and illuminate the specimen. They can achieve much higher magnifications than light microscopes, but they also require special equipment and techniques to prepare the specimen for viewing.

Fluorescence microscopes use fluorescent dyes to label specific structures or molecules in the specimen, which can then be visualized using a special filter. This technique is useful for studying specific structures or processes within a cell or tissue.

In a microscopy lab report, the student should first describe the equipment and techniques used to prepare and view the specimen. This should include details about the type of microscope used, the type of sample, and any special techniques or stains used to prepare the sample.

Next, the student should describe the results of the experiment, including any observations made about the specimen. This should include detailed descriptions of the structures or features observed, as well as any measurements or other data collected.

Finally, the student should discuss the implications of the results, including any conclusions that can be drawn based on the observations made. This may include discussing the importance of the structures or processes observed, or comparing the results to previous research on the same or similar topics.

Overall, a microscopy lab report is a detailed account of an experiment using microscopy to study small structures or organisms in biology. It should include a clear description of the equipment and techniques used, a thorough analysis of the results, and a discussion of the implications and significance of the observations made.

Body tube: It is a metal tube blackened inside. Part 6: Stereoscopic Dissecting Microscope Your instructor will demonstrate proper use of the dissecting scope. Illuminating apparatus condenser : It is fitted below the stage and provided with an iris The opening of the diaphragm can be reduced or even closed completely. Microorganisms are organisms that are too small to be seen with the human eye. To determine field of view. In this experiment, we used compound light microscope and stereomicroscope.

Turn on the light and open the diaphragm to produce a bright circle of light. In artificial light the plain surface is used. The base is either a horse-shoe or rectangle in shape. Place the scope back in its original space in the cabinet. The compound light microscope is an instrument containing two lenses, which magnifies, and a variety of knobs to resolve focus the picture.

Part 3: Field of View The field of view is the amount of the specimen you see when you look through the objectives. Find the number under your bench and use the corresponding microscope. This is because microscopes help scientist to examine specimen in more detail does not matter if it is a biological sample, plant sample or crystal structure. The stage is firmly secured with the arm. That means that 90% of the cells found in the human body are not human! Images observed under the light microscope are reversed and inverted. This is a huge field for such small subjects.

Be sure to cite the original source not yourself. This means that two objects that closer than 0. In order to see finer details of those microscopic objects our unaided eye need the help of other apparatus such as microscopes. Microscopes range from a simple magnifying glass to the expensive electron microscope. It is estimated, for example, that in the human body alone there are 10 microorganisms for every one human cell. These microscopes generally give a lower magnification than the compound microscope you are using. The eyepieces lens also has 10x magnification so the total magnification for this compound light microscope are 40x 4x10 , 100x 10x10 , 400x 40x10 , 1000x 100x10.

Looking through the eyepiece, move the slide to the upper right area of the stage. Procedure Place a blue plastic ruler across the stage aperture so that the edge of the ruler is visible as a vertical line along the field diameter. Our mission is to provide an online platform to help students to share notes in Biology. Draw what you see in the space below. . Add a drop of water. Move the slide to bring the portion of the object to be studied to the centre of the field.

Show your formula and all work. Its primary purpose is to show whether the problem statement methods are credible enough. Draw what you see in the space below. . For sharp focusing use fine adjustment. Write out the rule for determining total magnification of a compound microscope. The field of view decreases at higher magnifications.

Looking through the eyepiece, move the slide to the upper right area of the stage. It is a rather simple piece of equipment to understand and use. Since you are viewing larger samples, the magnification range of the dissecting microscope is lower than the compound light microscope. Both the object to be stuĀ­died and the microscope are placed directly on the dissecting tray in case of a horse-shoe base. Turn off the microscope and wind up the wire so it resembles its original position.

Binocular Microscope: In shape it is almost similar to a compound microscope, without a nose piece and it is of less height. Lower the low-power objective until it is 1 cm from the stage. Oculometre: It is a piece of thin, circuĀ­lar glass disc with a diameter of about 15 mm. Fill in the table on the next page to help you remember this important information. One of the main differences between primary and secondary journal articles is their source. Part 1: Total Magnification Magnification is the ratio of the image size with the microscope to the actual size of the object.

Estimate the field size in millimeters for each of the objective lenses. You will likely refer back to this page frequently. Try to place the coverslip on at an angle to avid air bubbles. It usually includes the sampling method, experimental design, analytical tools i. These microscopes give about ten to twentyfold magnification. Result: After the staining process, the gram-positive bacteria will appear purple, while gram-negative. Draw the image you see of the letter e or part of it on high power.
