Answer
Advancement in microscopy revolutionized cytology:
- Light Microscopy (17th century): Robert Hooke (1665) first observed dead cork cells; Anton van Leeuwenhoek examined living microorganisms
- Improved Staining Techniques: Differential staining revealed cellular components
- Electron Microscopy (1930s-1940s):
- Transmission Electron Microscope (TEM): Resolution up to 2 nm, revealing ultrastructure of organelles
- Scanning Electron Microscope (SEM): 3D surface imaging
These technological advances enabled visualization of subcellular structures, membrane systems, and molecular organization.
