The image of a walnut pollen in the scanning electron microscope.
This small pollen is not even half a millimetre in size: it’s diameter is approx. 40 µm.
Common Applications:Since pollen is very resistant to decomposition, pollen analyses can contribute to the analysis of current as well as historically ancient vegetation and ecosystems.
Microscopic analysis of the pollen population found in honey is the method of choice for determining the source of different honey varieties.
