  • Lab Report Compound Light Microscope

    Purpose: Observe a compound light microscope to learn the names of its major parts. Research: Microscope is an essential tool for the study of small structures such as cells. The most common type of microscope is the bright-field microscope, used for this purpose is the compound light microscope, it is called compound because it uses two sets of lenses the objective and the ocular. The ocular lens usually magnifies 10x. The objective lens can magnify 4x, 10x, 40x, or 100x. Hypothesis: To examine the slide of the three colored threads, and the…

  • Cellular Theory Essay

    Cellular Theory & Microscopes Robert Hooke Robert Hooke was an English scientist credited most famously for the creation of Hooke’s Law (a principle of physics that states that the force needed to extend or compress a spring by some distance is proportional to that distance) in 1660 and the discovery of plant cells using a compound microscope in 1663. The compound microscope uses two or more lenses, which are connected by a hollow tube. The top lens (called the eyepiece) is the one that people…

  • Inverted Fluorescence Essay

    An inverted fluorescence microscope is an inverted compound light microscope equipped with modules to internally separate the different wavelengths of light, and direct them to respective detection channels. Its main components include a light source, an objective, a filter cube and a detection unit, which can be an eyepiece or a camera (Fig.1). Filter cube is a component which separates a fluorescence microscope from a light microscope. It consists of one excitation filter, one emission filter…

  • Similarities Between Plant And Animal Cell

    Observation of plant and animal cells through a light microscope. A cell is the most basic structure of any living organism and is capable of independently reproducing. Cells can be grouped into two categories, prokaryotic and eukaryotic. In a eukaryotic cell there are small organelles that carry out specific functions which can be compared to the organs in the human body. Some of these organelles include the nucleus, which holds the cells DNA, mitochondria, which produce ATP from glucose and…

  • Pathogenesis Of Endometriosis Summary

    For the purpose of this assignment, I researched an article titled, “The Role of DJ-1 in the Pathogenesis of Endometriosis” by Priyanka Rai and Sisinthy Shivajj. The article discusses many components in which are relevant to the disease, endometriosis. Endometriosis is a disease among women in which causes infertility and severe pelvic pain along with other health concerns. It is seen to occur within 10% of woman whom are of a reproductive or sexually-active age. It is due to the occurrence…

  • Exercise 2: Observing Bacteria Cultures In Yogurt

    bacteria under the microscope with the resolutions 10x, 40x, and 100x with the use of immersion oil. Observations were noted and we replaced that yogurt slide with the prepared, stained yogurt slide. We compared and noted the observations between the two yogurt samples. Exercise 3: Preparing and Observing a Blood…

  • Ultrafast Electron Microscopy Analysis

    photocathode inside the microscope by UV laser pulses. These electron pulses are accelerated inside the microscope and incident on the sample under study together with visible laser pulses. The photon-electron coupling between the optical pulses and the electron pulses takes place when the energy-momentum conservation condition is satisfied (27, 28). This inelastic interaction leads to gain/loss of photon quanta via electron packets, which can be resolved in the electron energy spectrum…

  • Microscope Lab Report Essay

    During the microscope lab, my partner and I learned how to properly use a microscope, calculate the field of view, and view and prepare slides. Microscopes are instruments used to view very small objects that cannot be seen with the naked eye. We found that microscopes have many different parts to them, including the diaphragm, ocular lens, and objective lenses. There are three powers of magnification, scanning power (4x), low power (10x), and high power (40x). To find the total magnification,…

  • Wet Mount Slide Essay

    The slide used during the Microscope Lab was a wet-mount slide which was used in order to view the specimens from the microscope. A wet-mount is a method for preparing specimens to view using a microscope. A myriad of specimens look better when placed in a drop of water on the microscope slide. The water supports the sample and fills the space between the coverslip and the slide. This allows light to pass easily through the slide, the sample, and the coverslip. Scientists use the wet-mount…

  • Essay On The Relationship Between Chitin And Pathogenesis

    There was an extra control slide so that the microscope could be adjusted without harming the samples. The cover slip was placed on top and nail polish was added to the sides of the cover slip to prevent the sample from drying out. With the 40x lens of the Zeiss Axiovision Widefield Fluorescence Microscope, images of the cells were captured. The two channels that were used were DAPI and DIC. DAPI had an exposure time of 960,000ms per picture and DIC had an exposure time of 7200ms per picture.…
