Based on what you know about the differences between light microscopy and transmission
electron microscopy, indicate which technique would be best for visualizing each structure or
phenomenon listed below and why. lf light microscopy is best, which particular techniques (darkfield,
phase-contrast, etc)would be most useful?

-motion of chloroplasts in plant cells
-viral particles
-motion of bacterial cells
-cells containing specific protein in a tissue such as brain

Svar:

Motion of chloroplasts in plant cells – Phase Contrast
Viral Particles – Transmission Electron Microscope
Motion of bacterial cells – Phase Contrast
Cells containing specific protein in a tissue such as the brain – Fluorescence Microscopy
