A microtome is a mechanical instrument used to cut biological specimens into very thin segments for microscopic examination. Most microtomes use a steel blade and are used to prepare sections of animal or plant tissues for histology. The most common applications of microtomes are:\n\nTraditional histological technique: tissues are hardened by replacing water with paraffin. The tissue is then cut in the microtome at thicknesses varying from 2 to 25 micrometers thick. From there the tissue can be mounted on a microscope slide, stained and examined using a light microscope

Hi ya\nYes every thing is changing in this world even when i am writing this for you. Our body is changing continously even while we are sleeping and no cells remain same. Yes most of these things can be seen by microscope but some cant be. Even the Dead cells are getting replaced by the new one and wit every second a new life is begaining and some where  its finishing. But dont worry, we usually dont care as we get used to these things and many time we dont even care. Hope this will answer you.\ntake care

(m)\n\nField of View or Field Diameter is very important in microscopy as it is a more meaningful number than "magnification".  Field diameter is simply the number of millimeters or micrometers you will see in your whole field of view when looking into the eyepiece lens.  It is just as if you put a ruler under the microscope and counted the number of lines.  \n\nThe chart below will tell you (approximately) what to expect when looking through a microscope with varying combinations of eyepiece and objective lenses.  As an example (in green below), a dual power stereo microscope with 10X eyepiece lenses and 1X and 3X combinations of objective lenses, would have total powers of 10X and 30X and your field of view would be 20 mm and 6.7 mm respectively.  \n\nThis means that an object 20 mm (2 cm, or about 3/4 inch) wide would fill up the whole viewing area at 10X and an object about 6.7 mm wide would fill up the whole area at 30X.  As you can see, having the highest power may not be best for your particular application.  When you move to greater magnifications, you sacrifice field of view.

The parts of the microscope\nAt the top of the microscope is the eyepiece or ocular - a cylinder containing two or more lenses to bring the image to focus for the eye. The eyepiece is inserted into the top end of the body tube. This design allows for different eyepieces to be inserted to give different magnifications. Typical values for eyepieces include X5, X10 and X20. At the lower end of the microscope tube are one or more objective lenses mounted on a circular nose piece. Each objective lens is cylindrical and is screwed into to the nose piece. Typical values of objectives are x5, x10,x20, x40, x80 and x100. Below the objectives is the stage which supports the specimen being viewed. In the centre of the stage is a circular hole through which light shines to illuminate the specimen. Below the stage, the light is provided and controlled in a variety of ways. At its simplest, daylight is directed via a mirror. Most microscopes, however, have their own controllable light source that is focused through an optical device called a condenser with diaphragms and filters available to manage the quality and intensity of the light.\n\nThe whole of the optical assembly is attached to a rigid arm which in turn is attached to a robust U shaped foot to provide the necessary rigidity. The arm is usually able to pivot on its joint with the foot to allow the viewing angle to be adjusted. Mounted on the arm controls for focusing are usually placed, typically a large knurled wheel to control coarse focusing together with a smaller knurled wheel to control fine focusing.\n\nCompound optical microscopes can produce a magnified image of a specimen up to 1000× and, at high magnifications, are used to study thin specimens as they have a very limited depth of field. Typically they are used to examine a smear, a squash preparation, or a thinly sectioned slice of some material. With a few exceptions, they utilize light passing through the sample from below and special techniques are usually necessary to increase the contrast in the image to useful levels (see contrast methods). Typically, on a standard compound optical microscope, there are three objective lenses: a scanning lens (5×), low power lens (10×) or sometimes medium power lens (20x), and high power lens (40×). Advanced microscopes often have a fourth objective lens, called an oil immersion lens. To use this lens, a drop of oil is placed on top of the cover slip, and the lens moved into place where it is immersed in the oil. An oil immersion lens usually has a power of 100×. The actual power or magnification is the product of the powers of the ocular (eyepiece), usually about 10×, and the objective lens being used.

Sounds like something more serious. see a md.

I think it's an interesting picture. \n\nHey, what do YOU think of this? http://surgery-graphics.med.umich.edu/~matt/archives/images/Ladybug.jpg

It should be on a sticker somewhere on the 'board. Torch and magnifying glass time ... :-)

id say the plants and animals are multi-celled and the others are single-celled. also cell specilization could be a difference.

sounds really interesting.

a compound microscope consists of an objective lens and an eyepiece lens.both are double convex lenses.the focal length of the eyepiece is slightly greater than that of the objective.hope that answers your question

C\n\nThe ribosomes are far to small to see with a ligh microscope. Under an electron microscope, they look like tiny dots (of whatever color you stained them).\n\nAlso, you won't be able to make out the details of the cell membrane either, only that it exists.

well, you kinda answered your own question. The laser optics refers (here) to the use of mirrors to focus the light on the sample, this is normally used for a fluorescent dye which has been used to stain a part of the cell.

I could look at it and give you an opinion.
