Ovariole (IMAGE)
Caption
Insect ovaries are composed of tubes, called ovarioles, one of which is shown here. It is stained with a mitochondrial membrane-potential stain. The more red/white the color is, the higher the mitochondrial membrane potential, and in turn the higher mitochondrial activity it represents. You could think of this as a heat scale with the white/red colors being the most active and the blue/black colors having the lowest activity. Image is provided courtesy of Matthew Sieber.
