Figure 239 from Chapter 7 (Mitochondria) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. The cristae of mitochondria can take on zig-zag configuration (see arrows) which is particularly apparent in cel...

Mitochondria can show tremendous variation in size, even within a single cell. Here, a huge spherical mitochondria of about 6-7 µm in diameter is adjacent to small elongate mitochondria 0.5 µm wide...

The internal structure of mitochondria can change in response to physiological demand. Here, after the Sheepshead minnow Cyprinodon variegatus was kept in constant light for 4 weeks, mitochondria fro...

In the basal region of polarized epithelium engaged in ion transport, mitochondria are lodged between the interdigitating membranes of neighboring cells. This example is of a transverse section throu...

The high wing beat frequency in insects is intense muscle work, and dependent on a ready supply of ATP. This micrograph of flight muscle from the moth, Phytometra gamma shows the physical relationship...
