The biggest disadvantage of an electron microscope in the study of cells is that the cells must be fixed and prepared prior to viewing. Since many of the questions about cell function relate to the dynamic change of cells this is good reason to use other tools for this kind of research.

Advantages of light microscope over elctron?
You mean "electron," of course. There are a number of "advantages," but this is really not the right way to look at it, so to speak. The most obvious one is color. Electron microscopes cannot detect color because they do not use light to illuminate the object, they use electrons. Depending upon what one is looking for, color contrasts can be very important. Electron microscopes have their own advantages, primarily much higher magnification.
How do they various kinds of microscopes differ as tools in the study of cells?
Different types of microscopes, such as light microscopes, electron microscopes, and scanning probe microscopes, vary in terms of their magnification power and resolution. Light microscopes are commonly used to study living cells and tissues, while electron microscopes provide higher magnification and resolution to view detailed structures of cells. Scanning probe microscopes can provide information about surface topography and properties at the nanoscale. Each type of microscope has its own advantages and limitations in studying cells.
What are examples of non-optical microscopes?
Examples of non-optical microscopes include scanning electron microscopes (SEM), transmission electron microscopes (TEM), and atomic force microscopes (AFM). These types of microscopes use electron beams or probe tips to create high-resolution images of samples at the nanoscale level.
What are some disadvantages of the microscope?
Some disadvantages of microscopes include limited depth of field, potential distortion of the sample due to the lens, and the need for careful sample preparation and handling. Additionally, high-quality microscopes can be expensive and require maintenance and calibration.
What types of microscopes could be used to study viruses?
Electron microscopes, such as transmission electron microscopes (TEM) and scanning electron microscopes (SEM), are commonly used to study viruses due to their high magnification and resolution capabilities. These types of microscopes allow scientists to visualize the detailed structure and morphology of viruses at the nanometer scale. Light microscopes may also be used to study larger viruses.
What are the advantages of electron microscopes?
Electron microscopes provide high resolution images, allowing for visualization of small details at the nanometer scale. They have a greater magnification power compared to light microscopes, making them suitable for studying ultrafine structures. Electron microscopes can also provide information on the composition of materials through energy-dispersive X-ray spectroscopy.
What are the advantages and disadvantages of stereo microscopes?
advantages: you can clearly see the color of the object. you can use living samples it requires little or no preparation of the sample disadvantages: uses low magnification
What do scanning electron microscopes and transmission electron microscopes have in common?
Scanning electron microscopes and transmission electron microscopes are both types of electron microscopes that use beams of electrons to create detailed images of tiny objects at a very high magnification.
What are the Advantages of electron microscope over light microscope?
Electron microscopes offer much higher resolution and magnification capabilities compared to light microscopes. They allow for visualization of smaller structures and details, such as individual molecules, viruses, and cell organelles. Electron microscopes also have the ability to produce 3D images and can differentiate between materials based on their electron densities.

Which of the following is a lens found on electron microscopes but not on light microscopes?
An electromagnetic lens is found on electron microscopes but not on light microscopes. Electromagnetic lenses use magnetic fields to focus electron beams in electron microscopes, allowing for higher magnification and resolution compared to light microscopes.
What do scanning electron microscopes and transmission electron microscopes have in common?
Both scanning electron microscopes and transmission electron microscopes are types of electron microscopes that use beams of electrons to image samples at a high resolution. They both have higher magnification capabilities compared to light microscopes, allowing for detailed views of the structure and composition of samples at a nanoscale level.
What are the 2 main types of microscopes?
light microscopes and electron microscopes
What is the difference between electron microscopes?
Electron microscopes and what ... Light microscopes produce magnified images by focusing visible light rays. Electron microscopes produce magnified images by focusing beams of electrons
What kind of microscopes use beams of electrons to produce magnified images?
Electron microscopes use beams of electrons to produce magnified images. There are two main types: transmission electron microscopes (TEM) and scanning electron microscopes (SEM). They are capable of achieving much higher magnifications and resolutions compared to light microscopes.
What are two types of electron microscopes?
Two types of electron microscopes are the scanning electron microscope, or SEM, and transmission electron microscope, or TEM.
