A fluorescence image showing two curved, kidney-shaped plant guard cells forming a stomatal pore. The cells glow in bright magenta, outlining their overall shape, while clusters of distinct round and irregular structures inside them fluoresce green and yellow. The background is completely black.
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.
