\n
\nQ: How do scientists stain cells?
\n
\nA:
\n1) To begin you must prepare the slide you would like to examine. Label the slide with the specimen\u2019s name and then take measures to ensure that no bacteria will contaminate the specimen (avoid contact with potentially contaminated surfaces). Then transfer the specimen to a glass microscope slide by making a thin smear on the slide.
\n2) Then wait until the liquid dries and then heat fix the slide by waving it over an open flame.
\n3) Place slide on drying rack.
\n4) Flood slide with stain.
\n5) Finally, rinse slide in distilled water and let dry before viewing.
\n
\nQ: Why do scientists stain cells?
\n
\nA:
\nScientists mainly stain cells because many cells are unable to view without staining because they are see-through. Also, cells are stained because it is an easier way to view specific parts of a cell by colouring it so it is more defined compared to the rest of the cell.
\n
\nQ: Do cells need to be stained before being viewed under a microscope?
\n
\nA:
\nSince cells are transparent, it is a good idea to stain a cell before being viewed under a microscope because without the stain the cell would either be invisible or just one colour. The stain creates defined parts (or sometimes the entire cell) in a different colour creating an easier way to study the specimen.","dateCreated":"1349223347","smartDate":"Oct 2, 2012","userCreated":{"username":"Emilyk33","url":"https:\/\/www.wikispaces.com\/user\/view\/Emilyk33","imageUrl":"https:\/\/www.wikispaces.com\/user\/pic\/1362705197\/Emilyk33-lg.jpg"}},{"id":"57024548","body":"Microscopes:

\n
\nQ:How was the microscope invented?
\n
\nA: Glass had been invented and the Romans were experimenting with them during the 1st century AD. They noticed that if you put the lenses over an object, the object would look larger.Then sometime, about the year 1590, two dutch spectacle makers and there father started experimenting with the lenses and when they put a bunch of lenses in a tube, they realized the object would look much larger than any simple magnifying glass could do by itself
\n
\nQ:How is a microscope used?
\n
\nA:
\n1. Turn the revolving nosepiece so that the lowest power objective lens is "clicked" into position (This is also the shortest objective lens).
\n
\n2. Your microscope slide should be prepared with a coverslip or cover glass over the specimen. This will help protect the objective lenses if they touch the slide. Place the microscope slide on the stage and fasten it with the stage clips. You can push down on the back end of the stage clip to open it.
\n
\n3. Look at the objective lens and the stage from the side (Figure 2) and turn the coarse focus knob so that the objective lens moves downward (or the stage, if it moves, goes upward). Move it as far as it will go without touching the slide!
\n
\n4. Now, look through the eyepiece and adjust the illuminator (or mirror) and diaphragm (Figure 3) for the greatest amount of light.
\n
\n5. Slowly turn the coarse adjustment so that the objective lens goes up (away from the slide). Continue until the image comes into focus. Use the fine adjustment, if available, for fine focusing. If you have a microscope with a moving stage, then turn the coarse knob so the stage moves downward or away from the objective lens.
\n
\n6. Move the microscope slide around so that the image is in the center of the field of view and readjust the mirror, illuminator or diaphragm for the clearest image.
\n
\n7. Now, you should be able to change to the next objective lenses with only minimal use of the focusing adjustment. Use the fine adjustment, if available. If you cannot focus on your specimen, repeat steps 4 through 7 with the higher power objective lens in place. Do not allow the objective lens to touch the slide!
\n
\n8. The proper way to use a monocular microscope is to look through the eyepiece with one eye and keep the other eye open (this helps avoid eye strain). If you have to close one eye when looking into the microscope, it's ok. Remember, everything is upside down and backwards. When you move the slide to the right, the image goes to the left!
\n
\n9. Do not touch the glass part of the lenses with your fingers. Use only special lens paper to clean the lenses.
\n
\n10. When finished, raise the tube (or lower the stage), click the low power lens into position and remove the slide.

\nWhen is stain used?
\n
\nStain is used to enhancing cells that are transparent. Once you put the stain on the cell it becomes visible.

\nHow is stain used?
\n
\nStain is used for making cells more apparent so you are Abel to see them better.
\n
\nWhy is stain used?
\n
\nStain is used to make cells and the nucleus bigger and easier to see. When you use stain it dyes the cell to make it so you can see it better and have a clearer understanding of the cell when you see it clearer.
\n
\nHow is stain used when dying the cells make it easier?
\n
\nThe stain makes it easier to look at cells because the cells are clear(transparent) and harder to see with a lower grade microscope, so you have to put the cells in the Stain so you can see it with Omer detail.","dateCreated":"1349357255","smartDate":"Oct 4, 2012","userCreated":{"username":"alexB39","url":"https:\/\/www.wikispaces.com\/user\/view\/alexB39","imageUrl":"https:\/\/ssl.wikicdn.com\/i\/user_none_lg.jpg"}},{"id":"57048836","body":"1.Q.

\n
\nQ: how many parts are there of a microscope?
\nA: there are 13 parts of a microscope
\n Tube- the tube separates the ocular lens from the objective lenses at a distance calculated for proper magnification.
\n
\nRevolving nosepiece- this is where the objective lenses are mounted. Rotate the lens to select low,medium, or high power lenses.
\n
\n Objective lenses- there are three lenses that magnify the specimen:low power (4x) medium power(10x) and high power (40x). Keep the lenses free of dirt and Fingerprints.
\n
\n Stage clips- these are used to hold. Slide in a position on the stage.
\n
\n Stage- this is where you place a slide for observation, always keep the stage dry.
\n
\n Diaphragm - this has different sized holes that let different amounts of light pass through the specimen on the stage
\n
\n Condenser lens- this lens is under the stage. It helps focus light onto the specimen on top of the stage.
\n
\n Lamp-the lamp supplies the light that passes through the specimen on the stage. Microscopes that so do not have a lamp may have a mirror to collect the direct light.
\n
\n Base- this provides a stable platform for e microscope. Always set it on a flat, dry, uncluttered surface.
\n
\n Fine adjustment knob- use this lens to sharpen an image under low and medium power.it is the only adjustment knob needed with the high power lens.
\n
\n Coarse adjustment knob- this knob moves the stage up or down to focus on the specimen. This is the first knob you use to focus on a specimen.
\n
\n Arm- the arm holds the tube in place and is used to carry the microscope.
\n
\n Eye piece- this is the lens that magnifies the specimen, usually by 10 times (10x) this is the lens you look into.
