What improvements to technology contributed to the development of the cell theory?

Answer 1

Electron microscope.

With its extremely high magnification and high resolution, the electron microscope was essential for viewing the endoplasmic reticulum, nucleolus, ribosomes, and many other smaller components of cells. Without it, the development of cell theory would not have been possible.
