Describe an advantage of using TEM rather than LM to study intracellular structure.
To determine :
The advantage of using TEM instead of LM to study intracellular structure.
Introduction:
TEM stands for transmission electron microscope while LM stands for the light microscope. The transmission electron microscope is used to form an image of the specimen by the transmission of a beam of electrons through the specimen. The light microscope uses magnifying glasses and visible light to examine the specimen.
Explanation of Solution
The transmission electron microscope provides greater magnification and resolution than the light microscope to study intracellular structure. TEM gives 1000 times better resolution than the light microscopy, so it is better to use a transmission electron microscope instead of using a light microscope. TEM provides the details of the structure inside the cell or structures which are attached to the cell surface.
