Microscope Familiarization

Purpose: The purpose of this lab is to help familiarize myself with the microscope.
Problem: What are the appropriate procedures when using the microscope?
Materials: Computer, Paper, Pen, Laboratory Manual, Thread, Hair, Microscope, Slide, Slide Cover, Small Glass Bottle, Dropper, and water.
Procedure: I started by logging into the computer and completing the training module online. Then I went to the cart and brought the microscope over to my work area, making sure to carry the microscope by the arm and base. I uncovered and plugged in the microscope. I then went back to the cart and got a slide and slide cover, as well as a small glass bottle and dropper. I filled the small glass bottle with water and took everything back to my work area. I wrote a letter e on a piece of paper with a pen, pulled a strand of hair from my head and pulled a string off of my jacket. Then I turned on the microscope, prepared my slide and proceeded to look at each object under the microscope.
Data: If the slide was too close or too far from the lens than you will not be able to see the specimen. The larger the magnification on the microscope the more detail that can be seen. The course and fine adjustment knobs move the slide up and down to help focus the specimen on the slide. The mechanical stage controls move the slide left and right, and forward and backwards.
Findings: While observing the hair under the microscope I noticed that it is not smooth. The hair actually looks like it is made up of tiny scales. While observing the paper with the letter e written on it, I noticed that, just like the hair, the paper does not look smooth. The paper actually looks like a bunch of threads woven together like a birds nest. The ink on the paper only seemed to stick to the top layer or two of the paper material. I also observed that the letter appeared upside down and backwards to what it was on the slide. While observing the thread I could see that like the hair and paper it was made up of many smaller strands. Although unlike the hair and paper the threads strands were all parallel and ran in the same direction.
Conclusion: In conclusion, when you are able to properly adjust the microscope you can see many interesting characteristics just about any organic or inorganic material. I learned that different materials, although appearing smooth to the naked eye, are actually rough under the microscope. I also learned that things seen under the microscope appears upside down and backwards from how it is placed on the slide. I learned that larger notifications show more details than smaller magnifications.

How To Write A Lab Report On Chloroplast Organelles In Plant Cells

...The most interesting thing I observed in today’s microscope lab was that I was able to view algae from a sample of pond water. The total magnification which I made the observation was 450. Been able to see algae just with the sample of pond water is amazing because whenever I see pond water I never think about what it beholds I just thought of it as water and nothing spectacular. 2. In the plant cell I observed the chloroplast organelle. My observations for the chloroplast organelle was that the shape was a circle and very tiny. I also I learned that the function of the chloroplast organelle is to conduct photosynthesis. In the animal cell I observed the nucleus. My observations for the nucleus was that the shape was a oval. When you look through the microscope it looks like a nucleus inside of the nucleus. I also I learned that the animal cell of the nucleus is to hold genetic code (DNA). 3. If I looked at bacterial cells with the microscope, I would expect to see neither one. Due to bacteria is a prokaryotic cell. Though, bacteria cells is a living...

...was a basket-maker, while his mother's family were brewers. Antony was educated as a child in a school in the town of Warmond, then lived with his uncle at Benthuizen; in 1648 he was apprenticed in a linen-draper's shop. Around 1654 he returned to Delft, where he spent the rest of his life. He set himself up in business as a draper (a fabric merchant); he is also known to have worked as a surveyor, a wine assayer, and as a minor city official. In 1676 he served as the trustee of the estate of the deceased and bankrupt Jan Vermeer, the famous painter, who had had been born in the same year as Leeuwenhoek and is thought to have been a friend of his. And at some time before 1668, Antony van Leeuwenhoek learned to grind lenses, made simple microscopes, and began observing with them. He seems to have been inspired to take up microscopy by having seen a copy of Robert...

Spectromotography Paper

...tend to move around when dissolved in a solution is because all molecules display random thermal motion and have kinetic energy. Kinetic energy is what allows the molecules to diffuse down a gradient of high concentration to regions of low concentration until the distribution of molecules become equal and achieved dynamic equilibrium. The entire solution only becomes homogeneous when one of the several factors are reached: the size of the dye molecules, temperature of the solution, density of the solvent and concentration of the dye. Heat is what causes random motion of molecules and passively moves molecules in biological systems. However, we can’t see this movement with our naked eye. In order for us to see this movement, we must use a microscope to see the small particles move after collision, this is called the Brownian movement. When talking about the cell membrane we must understand that it is selectively permeable, which means it can choose what can pass through the membrane and what can’t. Polarity and size are he two most important characteristics of molecules govern their passive movement through a lipid membrane. Dialysis tubing is what we are going to be using in our second procedure to model a selectively permeable membrane. Dialysis is the separation of dissolved substances by means of their unequal diffusion through a selectively permeable...

M2D1 Microscopy and Differential Staining

...M2D1: Microscopy and Differential Staining 1. What are the advantages and disadvantages of the different types of light and electron microscopes discussed in Chapter 3 that are used to study microorganisms? Focus your response in terms of the following parameters: o Range of magnification o Resolving ability o Sample preparation o Possible states of sample (e.g. whole organism, part of, living, non-living, etc Compound Light microscopes magnification is 2000X. Resolution of about 0.2μm. Can only see very small specimens and specimens are stained. Darkfield – used to study live microorganisms that cannot be stained or staining distorts the image or they are invisible using the normal light microscope. Phase-Contrast – in living microorganisms, this scope allows you to see detailed internal structures, plus you do not have to fix or stain the microbes. Differential Interference Contrast (DIC) – instead of one beam of light, 2 beams are used. Image looks almost 3-dimensional and is brightly colored. Fluorescence – used mainly as a diagnostic technique. Stained with fluorochromes and viewed with an ultraviolent light. Confocal – makes 3-dimensional images using a computer. Able to see entire cells and their components. Two-Photon – living cells can be seen up to 1mm (1000um) deep in tissues. Can also track, in real time, the activity of cells. Scanning Acoustic – living cells that are attached to cancer cells, artery plaque and biofilms can be seen......

...Compound Microscope Parts A high power or compound microscope achieves higher levels of magnification than a stereo or low power microscope. It is used to view smaller specimens such as cell structures which cannot be seen at lower levels of magnification. Essentially, a compound microscope consists of structural and optical components. However, within these two basic systems, there are some essential components that every microscopist should know and understand. These key microscope parts are illustrated and explained below. STRUCTURAL COMPONENTS The three basic, structural components of a compound microscope are the head, base and arm. •Head/Body houses the optical parts in the upper part of the microscope •Base of the microscope supports the microscope and houses the illuminator •Arm connects to the base and supports the microscope head. It is also used to carry the microscope. When carrying a compound microscope always take care to lift it by both the arm and base, simultaneously. Ocular with Pointer eyepiece which magnifies image projected by objective Body Tube maintains the correct distance between the eyepiece and the objectives (usually 25 cm) Arm supports the body tube and is used to carry the microscope Coarse Adjustment a knob that makes large adjustments to the focus Fine Adjustment a knob that makes small adjustments to the focus Nosepiece holds the objectives and can be rotated to change the magnification Objective......

Labset 2 Worksheep

...Labset Two Worksheet 1. What is differential staining? How does it differ from simple staining? (2) Differential staining uses more than one chemical stain. It can help differentiate between different microorganisms, or different parts of the cell. The simple stain uses one stain and is used to see cell shape and size. 2. What are the differences between gram positive and gram negative cell walls? (2) A gram positive has a thick wall of peptidoglycan and stains purple. A gram negative has a membrane covering the peptidoglycan and doesn’t stain leaving it a pink color. 3. What is a mordant? What serves as a mordant in the gram stain protocol? (2) A mordant is a chemical that can deepen the reaction of the dye. Iodine is the mordant in the gram stain protocol. 4. Why do gram negative cells stain pink? Gram positive cells purple? (2) Gram positive cells have cell walls and can retain the dye. Gram negative cells do not have cell walls and cannot retain the dye. Cristal Violet is added to the sample and penetrates the cell walls, staining the cell in the gram positive. Gram negative will not retain color as there is no cell wall. A counterstain is added to make the cell visible and turns it a pink. 5. What is measured by the methyl red portion of the MR-VP test? (2) It measures acid in a bacterial broth. It turns red in pH under 4.4, yellow in pH over 6.2, and orange in between. 6. What is measured by the......

...Living or Non-living? By: Chris Millard Biology 9-10A In class we have been looking at different substances under microscopes and under one there was a very weird substance. I’ve been thinking if this substance is a living or nonliving substance. I think it looked like it was a living substance. I’ve been researching and I have found many kinds of brown bugs. There were some bugs that I found that looked like of what I saw in class. When I looked through the microscope I saw some things such as, legs on the side on it, its body was shaped like a little circle, it had one long end, one round end with a brown color. There was one that was broken and had a sort of glossy substance. That substance is likely to be cells that are inside the bug that have been broken and separated out of it. To me that seems like some sort of like a grass hopper. I looked up a few different bugs and one that I did look up grass hopper. Grass hoppers can be small, brown and they also have a long body and a long front. All this research I did, lead me to believe that this substance was indeed a living organism. For it to be a living organism it must at least have cells, use energy, develop, reproduce, or adapt to their environment. A grass hopper has at least one of these characteristics. This research helped me a lot to figure out whether it was a living or nonliving substance. By finding the characteristics, it helped me understand that it was. I discovered it was a grass hopper. I now......

...on using the Microscope: The purpose for my manual topic is showing on how to use the microscope and also the assembly of a microscope when is taken out of the box. The very first and most important fact is picking a title that is clear on what it is going to explain. Also picking a readable font is really important for making the audience want to read the manual. At the beginning of my manual, I will have the table of content, which is the most basic part that a manual should have. The first part of my table content will include safety, which in my opinion is the most important fact using a product, although there is not that much peril utilizing a microscope. After safety, I will have the introduction, which will provide brief information about different types of microscopes and how they differ in terms of the purpose they are used. I also will give brief descriptions about what a microscope is and what is exactly used for; assuming part of the audience doesn’t know that much about microscopes. I will explain about parts of the microscope and what function they have; parts such as eyepiece, objective lens, focus adjustment knob, stand column, and etc. I will put a figure showing each part so the audience has a better understanding of the microscope. I will mention all the parts that are included in the box and all the extra equipment needed for the assembly of the microscope such as screwdriver. After all that, I will start with how to operate the microscope with a quick...

Molecular Biology pinched off containing the smaller particles turning into a vesicle which is taken where it needs to go. Question 5. A scientist might choose light-microscopy over electron microscopy because you can use living cells and watch how different factors affect them. Electron microscopy might be used because it has better resolution so you can see more details and depth to determine what the sample really looks like. Question 7. Basic light microscopes require chemical staining because most of the cells are not visible under normal light conditions. The cell material doesn’t absorb visible light so they look invisible. Another way of visualizing samples is by using fluorescence. Most of the chemical stains bind to the whole molecule or group of molecules instead of a specific part or specific molecule. You can go around this problem by using fluorescent microscopy. The fluorescent marker can be attached to a specific place or molecule so that you only see the part that you want too because if you are using a fluorescent microscope you will only see the part or molecule that fluoresces. Confocal scanning and deconvolution microscopy make fluorescent microscopy better by allowing you to focus on a specific region or depth of the sample. This makes what you see sharper and you can use this type of microscopy on thicker samples because you can focus on a more specific layer. Question 9. A cell line can keep dividing in the same sample so you continue to have live......

Bacterial and Blood

...Observing Bacteria and Blood Student Jamie Chrostowski Lab 1 – Due 2/15/15 Microbiology DL1, Professor Newton Abstract: The different objectives of a microscope allow for a range of observations. At the highest objectives, the resolution can easily be lost which is why the oil immersion lens is used to minimize refraction. While observing specimens, both dead and active, their shapes and arrangements can be observed. This allowed for hands on learning, observation, and identification of the bacterial shapes and arrangements. At the 10x magnification, generally the slides showed tiny dots or it was difficult to properly make any identification. At 100x magnification, identification of structures was possible, such as the nucleus. Purpose: The purpose of this experiment is to gain knowledge of the functions and operations of the compound light microscope and an immersion oil lens by observing prepared slides of various bacteria slides. Learnings also included the identification and observation of various shapes and characteristics of bacteria, as well as, yogurt cultures (fresh and prepared) under a microscopic view. Procedure: Exercise 1: Viewing Prepared Slides * The first step is to assemble the compound light microscope. * Next the slides and cover slips were cleaned for dust and other particles. * Once assembled, the prepared letter “e” slide was placed on the stage and adjustments were made to the condenser, diaphragm, and course/fine adjustment knobs...

Mlt-Task One

...Lindsay Wootton Clinical Microbiology Laboratory 211.2 Task 1 A. This experiment consists of four different activities. They include the fresh wet mount, direct staining using crystal violet and indirect staining using both Congo red, and crystal violet. A close examination of these examples showed that the wet mount slide examples were all the same in appearance. the cheek and yeast both appear to have some circular cells. the cheek smear was the most difficult to see. The direct staining images were very easy to make out the cells, as they turned the color of the crystal violet. The indirect staining, also known as the negative staining, used the Congo red dye and produced interesting results. The cheek smear looked like the cells were stained, rather than the background as it was explained in the experiment. It shows in the up close cheek smear, as the yeast smear didn't seem to retain the red color. It was however easier to make out the shapes of the cells. The plaque smear, retained some of the red dye but not in any sort of pattern in which to clearly be able to see cells. B. The bacterial morphologies, also known as the shape of the cells, were very easy to see with the crystal violet stain. The slides showed cocci and bacillus shaped cells. On the wet mount cheek smears it was hard to make out any shapes, but in the direct staining slides you could make out cocci shapes on the cheek and yeast smears. You could also make out some cocci on the......
