What microscope provides sharp pictures of three-dimensional structures at high magnification?
Scanning electron microscope-An electron microscope that forms a three-dimensional image on a cathode-ray tube by moving a beam of focused electrons across an object and reading both the electrons scattered by the object and the secondary electrons produced by it.
What forms the enlarged images produced by a microscope?
The Lenses
What is the clarity of the picture produced by a microscope called?
Magnificaton
The sharpness of an image produced by a microscope is called magnification.?
No. Magnification refers to how many times larger an image is made.The sharpness of an image produced by a microscope is called resolution.
Adenosine triphosphate is produced in greatest quantity during?
electron transport chain.
What is a characteristic of an image produced from a transmission electron microscope A. It is black and white. B. It shows the surface of objects. C. It does?
It is black and white.
What type of microscope can be used to study a viruses?
As viruses cannot be seen with the optical microscope, electron microscopes are used. All the "lenses" in an electron microscope are magnetic fields produced by electromagnets and/or electrostatic fields produced by electrically charged metal plates and/or rings.

What is used to bend electrons in an electron microscope?
Magnetic lenses are used to control the electron beam in an electron microscope. The magnetic field produced by the magnetic lenses deflects the energetic electrons. They are typically called magnetic lenses because they deflect the electron beam like optical lenses deflect light.
Why there is more detail in an image produced using a TEM than in the image from a light microscope?
An electron microscope is a microscope that uses beams of electrons instead of rays of visible light to form highly magnified images of tiny areas materials or biological specimens. Comparing light vs electron microscopes is made more complicated by the fact that there are different types of electron microscopes.

What are three uses of the Transmission Electron Microscope?
There are two types of electron microscopes: scanning and transmission. They function differently from regular ocular microscopes in that the focusing devices are not glass lenses. The focusing device is a beam of electrons in a vacuum tube focused between two large magnets, with the sample to be observed in the middle. Electron microscopes were built so that a sample could be studied not at the cellular level, but at the molecular level. It is possible to see actual molecules with an electron microscope. Scanning electron microscopes (SEM) examine the surface of the sample. The sample is first frozen in liquid nitrogen, then fractured so it spits in half, is then placed in the vacuum chamber of the scanning microscope and the electron beam scans the inner surface of the sample. The electrons are then digitized, sent to a computer and an image is produced. With transmission electron microscopes (TEM) the beam of electrons penetrates the sample - it is not a surface scan. Again, a biological sample is frozen in liquid nitrogen, then thin sectioned - cut into microscopically thin slices - then placed into the vacuum chamber of the TEM and the beam penetrates the sample to gain imagery of the molecular structure of the sample. The first million-volt electron microscope was developed by Jan LePoole, a Dutch physicist, during WWII in an effort to study metal fracture rates for bombs. He beat the Nazis in a race to build the two story microscope, won the Noble Prize and was knighted by the queen of the Netherlands. The major manufacturers of these microscopes are Philips, Hitachi, and Joel. Visit any of their websites. To learn more about scanning and transmission electron microscopes also visit the website of the Microscopy Society of America (MSA).
What are the differences between a light microscope a compound microscope a stereoscopic light microscope a transmission electron microscope and a scanning electron microscope?
A light microscope uses a series of lenses to focus light allowing small objects to appear larger. A compound microscope works as a light microscope except it uses more than two lenses to increase magnification. A stereoscopic light microscope can be simple (one lens) or compound (more than one lens) and uses two eyepieces.A transmission electron microscope requires the object be in a vacuum and stained (usually with a heavy metal). The microscope fires electrons at the target and measures the diffraction allowing for a computer to generate an image.A scanning electron microscope uses an electron beam to scan the target. It then generates an image by analyzing the variety of signals produced such as secondary electrons released, electromagnetic radiation, and electron deflection.Also an electron microscope can observe a centriole, a tiny structure found in animal cells. Also to break down what a compound light microscope does is that it uses light and a curved piece of glass to make tiny structures appear larger. We can also see many other objects throw a microscope by taking a piece of cut Glass taking for example a piece of string and adding a drop of water then adding a small plastic thing and putting it under a COMPOUND LIGHT MICROSCOPE!!!!!!
