Jack Pine Pollen - 30 kV

Pine pollen imaged at 30 kV

This image is an Environmental Scanning Electron Microscope (ESEM) image of some air-dried Jack Pine pollen grains collected from near Mio in Michigan.  The 30 kV electrons penetrate right through the pollen grains, giving the image an "X-ray" appearance where grains can be seen through each other.
