Question

Which method of microscopy is illustrated in this drawing?

A) Confocal microscopy
B) Transmission electron microscopy
C) Freeze-fracture microscopy
D) Scanning electron microscopy

Answer 1

The method of microscopy illustrated in the drawing is Transmission electron microscopy (TEM). TEM uses a beam of electrons to achieve high magnification and resolution, allowing us to see individual atoms and the structure of cell nuclei. It is especially useful for viewing thick structures such as biofilms.

Step-by-step explanation:

The method of microscopy illustrated in the drawing is Transmission electron microscopy (TEM).

TEM uses a beam of electrons that passes through a thin sample and is focused onto a detector. It can achieve high magnification and resolution, allowing us to see individual atoms and the structure of cell nuclei.

TEM is especially useful for viewing thick structures such as biofilms.
