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.

Figure 2: The structure of a mitochondrion. (A) Electron microscopy image of a mitochondrion from the pancreas of a bat. (B) Schematic illustrating the three membrane spaces relevant to mitochondria as well as the connectivity.(A adapted from D. W. Fawcett, The Cell, Its Organelles and Inclusions: An Atlas of Fine Structure, W. B. Saunders, 1966.).Beyond their fascinating ancestry, mitochondria are also provocative as a result of their great diversity in terms of both size and shape.igure 2: The structure of a mitochondrion.
