Mitochondria under the microscope. Microscopes have been crucial for our understanding of mitochondrial structure and function. Mitochondria are visible under the light microscope although little detail can be seen.Transmission electron microscopy (left) shows the complex internal membrane structure of mitochondria, and electron tomography (right) gives a three-dimensional view.itochondria under the microscope.

Matthias Schleiden Matthias Schleiden discovered that plants are made up of cells using a microscope. This supports the theory that all living things are composed of cells. Matthias also worked with Theodor Schwann in the year 1839 to compose two of the cell theory principals.ike Newton, the cell theory would not have been developed without the invention of the microscope. In order for Matthias Schleiden, Theodor Schwann, and Rudolf Virchow to create the cell theory, they needed the microscopes that Hans and Zacharias Jansen had invented prior to their discoveries.
