Question:
Scanning electron microscopes sem and transmission electron microscope ten have similarities and differences. Which of the following accurately states a how they differ
a.The TEM uses light and magnification to observe details of objects; whereas, the SEM produces images on a computer that can be colorized to enhance details.
b.The SEM is capable of magnification up to 1,000,000 X, whereas, the TEM magnifies an object up to 100,000 X
c.The TEM is useful for analyzing the internal organelles of a cells, while, the SEM gives a 3-D view of the external features of cells.
d.The SEM is used to view detailed images of live organisms, whereas, the TEM is only capable of viewing non-living organisms.
Answer:
Option c: The TEM is useful for analyzing the internal organelles of a cells, while, the SEM gives a 3-D view of the external features of cells.
Explanation:
The Transmission Electron Microscopes is used to visualise the "internal structure" of the cells. This works when an electron beam of light passes through the object or the sample, it shows a clear presence of the organelles inside the cell, whereas the SEM collects the scattered electron beam to visualise the objects, that’s why it can only show the outer surface of the cell and it also helps in figure out of the composition
