Question

1) When biologists wish to study the internal ultrastructure of cells, they can achieve the finest resolution by using A) a phase-contrast light microscope. B) a scanning electron microscope. C) a transmission electronic microscope. Dna confocal fluorescence microscope. E) a super-resolution fluorescence microscope.

Answer 1

Answer:

C) a transmission electronic microscope

Explanation:

The transmission electron microscope is a high quality instrument to study internal ultrastructure of cells. It uses high energy beam of electrons instead of light for the imaging of the objects. As the wavelength of electrons is less as compared to the light which gives very high resolution of the images. High resolution can be used to analyze ultrastructure of cells.  Thus, the finest details of internal structure of cells can be studied.
