Directions. 1  Heat oven to 400Â° F. Pierce each sweet potato several times with the tines of a fork. 2  Place the sweet potatoes on a rimmed baking sheet lined with foil. 3  Bake until tender, about 45 minutes. 4  Make a slit in the top of each sweet potato.
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.

View full size image. Mitochondria are specialized structures unique to the cells of animals, plants and fungi. They serve as batteries, powering various functions of the cell and the organism as a whole. Though mitochondria are an integral part of the cell, evidence shows that they evolved from primitive bacteria.itochondria are unlike most organelles (with an exception of plant chloroplasts) in that they have their own set of DNA and genes that encode proteins. Plant mitochondria were first observed by Friedrich Meves in 1904, as mentioned by Ernster and Schatz (Journal of Cell Biology, 1981).
