Importance of animal cells organelles and the role of the mitochondria in cellular respiration
Explain the key features and uses of light and electron microscopes [1.1]
The light microscope emphasizes over the visible lights by the help of specimen. Various regions related to the object scatter the light in different ways and produce an image. Light microscope use is limited. Light microscope has its limitations that imply that the user could only view the two-dimensional specimen plane at the single time. Through a light microscope, both fixed as well as light specimens could be studied, and it’s important that specimen should not be dehydrated (Campbell 2005). There is no cooling system in the light microscope, and risk of radiation is absent.
Electron microscope is referred as a device that can support in forming the magnified object images with the help of electrons. Two primary purposes are served by electron microscopes. The structural visual examination is too subtle to get resolved with a light microscope, and surface study can emit the electrons (Campbell 2005). It is evident that first function related to transmission electron microscopes is an essential research tool in biology. In the case of electron microscope the cooling system takes out the heat, which is generated by the high voltage electric current, and at the same time, it possesses the risk of radiation leakage.
