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.

Knott & Ruska shared Nobel Prize for developing electron microscope. More recent developments include use of polarised light, video and digitizers but light microscopes are still basically modelled on Van Leeuwenhoekâs. Cell background 1665 Hooke coined the term âcellâ, in his work Macrophagia. Cells in cork oak tissue reminded him of monksâ cells. 1831 Robert Brown first described a cell nucleus. 1839 Schwann proposed a theory that all living matter is cellular. 1860 Pasteur consolidated this and named it the âcell theoryâ. -1-
