How much are these onion cell magnified?
It depends on the strength of the lense you are using and how high you set the magnification of the microscope.At 40X magnification, the microscope enlarges a 2 mm part of the onion and at 100X the microscope enlarges 0.8 mm of the cell. At both 40X and 100X you can online see a zoomed out image of the cells.At 400X, the microscope enlarges a 0.2 mm part of the cell. The individual cell is more clearly seen.At 1000X magnification, the microscope enlarges a 0.08 mm part of the onion cell. At this level of magnification the nucleus of the onion cell can be seen.This link shows different magnifications of the onion cells.
What are 2 organelles that are not visible in a cheek cell?
A human cheek cell contains the same organelles as any other mammal cell and just about the organelles of any animal. It doesn't have several organelles, but the two physical characteristics present in a plant cell but absent in an animal cell are the chloroplast and central vacuole. The chloroplast carries out photosynthesis with its own set of DNA. The central vacuole contrasts with the many smaller vacuoles in an animal cell as the largest organelle in a plant cell. Vacuoles simply store fluids, most always water. Cell Wall is also not found in animal cells.
What is a compound light?
'Compound light' means a certain type of microscope, separating it from other types like digital microscope or electron scanning microscopes. Compound light microscope is the very traditional type used in laboratories. It has usually a set of lenses for different magnification levels (eg. 150x, 300x, 600x, 900x, 1200x) The object of study under the microscope can be illuminated in different ways to enable one to inspect certain characteristics better.
How is a stereo microscope different from a compound microscope?
Compound microscope - a microscope which uses multiple lenses to collect light from the sample, and then a separate set of lenses to focus the light into the eye or camera. It shines a light from beneath the stage, going up through the object being examined.Stereo microscope - a microscope designed for low magnification observation of an opaque object. It shines a light onto the object, rather than shining it up through the object. It uses two separate optical paths with two objectives and two eyepieces to provide slightly different viewing angles to the left and right eyes. This produces a three-dimensional visualization of the object.

Where could I get science toys for children?
You can buy a set of microscope for kids with 600x magnification at Toys "R" Us. The set contains not only the microscope but also some samples of plant skin and insect wings. It also has the chemicals needed to change the cell's nucleus' color for better view.
How do you determine what the magnification of the specimen is?
In a light microscope magnification is varied by using different lenses to refract the light. In an electron microscope magnification is varied by altering the configurations of magnetic fields to bend the electron beam.
How do you set up a microscope?
To set up a microscope follow these steps:Hold the microscope by its base.Place it near a light source. (Not directly in the sun.)Adjust the mirror until light is reflected up the microscpe. (Check this by looking done the microscope.)Turn the objective lens to its lowest magnification.
How do you set lenss if wants to give 40x magnification for the object?
in most microscopes there are 3 different lenses with 3 different strengths of magnification. The shortest one usually is X4 magnification, if you have the right lense at the top of the microscope, which should be a X10 lense, you will get a X40 magnification.

What are the steps to focus a microscope?
Depending on the microscope the steps differ but assuming you are using a light microscope (the only microscope you will use before university). The microscope must be set to the lowest magnification with the stage set as far way as possible (the platform the sample is held on). Then using the coarse focus (the larger knob) bring the stage towards the lens while looking though the eye piece when the sample comes into focus use the fine focus knob (the smaller knob) to bring the image to optimum focus. When this is achieved increases the magnification (by changing to a stronger lens) and using fine focus continue to focus the image and keep repeating the steps till a max focus is achieved. If more information is need let me know as there are more complicated techniques but this should be enough for before a university level depending on what country you are in.

Who discovered the simple microscope?
Short answer: Zacharias Jansen Long answer: Your question is not valid for 2 reasons: 1. You cannot "discover" something if it does not exist. You should be asking who invented it, not who found it laying around somewhere. 2. A "simple microscope" is not common terminology. Simple compared to an electron microscope? or simple compared to a compound microscope? What is typically referred to as just "microscope" is technically a compound microscope. A set of multiple lenses mounted in a desktop style that allows the compounding of magnification. A compound microscope is the standard microscope in any basic lab setting. Anything more "simple" than a compound microscope would not even really be a microscope, it would either be a telescope, or simpler than that is a magnifying glass (with a single lens) The inventor of the magnifying glass was: Roger Bacon The next step up is the telescope invented by: Zacharias Jansen The next step up is the "compound microscope" which was also invented by: Zacharias Jansen (this is the simplest form of what would be recognized as or named "microscope") If you wanted to go even "simpler" and define microscope as anything that magnifies, there were reading glasses around for thousands of years prior, and even "reading stones" which were lumps of polished glass used to magnify parchment in Egypt as far back as 7000 B.C. (inventor unknown). So it really depends on how you wish to refine your meaning of simple. The magnification of anything? There is no known inventor for reading stones, his name is lost to time. Or if you mean the first invented microscope that could examine things too small for a human eye to detect, that's a compound microscope. Thus if I am guessing your meaning correctly, you meant to ask this question: Question: Who invented the compound microscope? Answer: Zacharias Jansen
