I pulled this image from the archives of my PhD work, back when I was working with plant and yeast mitochondria.
These are two Arabidopsis guard cells, with their cytosol in magenta, mitochondria in yellow, and chlorophyll autofluorescence in green.

How do guard cells power stomatal movements?

Ditz et al. show that guard cell mitochondria display a protein composition consistent with optimized ATP production, highlighting cell-type-specific energy metabolism in plants.
