Which technique is best for observing the fine structure of cellular membranes?
A) Scanning Electron Microscopy (SEM)
B) Transmission Electron Microscopy (TEM)
C) Confocal Microscopy
D) Phase Contrast Microscopy
Explanation: TEM provides high-resolution images that are ideal for examining the fine structure of cellular membranes.
