Question

Which is a difference between a compound light microscope and a transmission electron microscope? A.The compound light microscope can only view specimens in black and white, while the transmission electron microscope has color.
B. The compound light microscope can view living things, but the transmission electron cannot.
C.The compound light microscope examines the surface of a cell, and the transmission electron microscope examines internal parts of the cell.
D.The transmission electron microscope is used for dissections, while the compound light microscope is not.

Answer 1

Answer:

While a light microscope uses light to illuminate specimens and glass lenses to magnify images, an electron microscope uses a beam of electrons to illuminate specimens and magnetic lenses to magnify images. The resolution (the level of image detailing) is the main difference between these two microscopes.

A compound light microscope is a microscope with more than one lens and its own light source. In this type of microscope, there are ocular lenses in the binocular eyepieces and objective lenses in a rotating nose piece closer to the specimen.

Answer 2

Answer:

Option B, The compound light microscope can view living things, but the transmission electron cannot.

Explanation:

In a transmission electron microscope(TEM) , a beam of electron is used to illuminate the specimen thereby generating its projection images.  While compound microscope uses light to illuminate the surface of specimen and hence magnify it (make it larger) and  observes its structure (even cells and their structure). Compound microscope has high magnification but low resolution while a TEM has high magnification and  high resolution. TEM requires vaccum environment to operate while this is not the case with compound microscope. TEM can be used to view dead things only while compound microscope is used to observe both dead and live things.

Hence, option B is correct
