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...

Steriod-secreting cells exhibit unusual diversity in the cristae of their mitochrondria, like these examples from testicular Leydig cells of the ground squirrel Citellus lateralis. Small alveolar cri...
