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.

Mitochondria, the energy powerhouses of cells, are distinct from other organelles because they have their own DNA. The genetic material is different from nuclear DNA and has led to the theory that mitochondria were once free-living and then ingested by bacteria.slide 1 of 4.itochondria are rod-shaped membrane-enclosed organelles that are found in the cytoplasm of most eukaryotic cells. Their size ranges from about 1 to 10 micrometers and they provide the chemical energy that cells need in order to be able to carry out their functions.
