A sad walnut pollen

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 Read more

Cress: puckered lips

An inconspicuous green cress leaflet reveals many interesting openings on the leaf underside within a scanning electron microscope: the stomata. These pores control the rate of gas exchange. The diameter of the shown stoma is about 8 µm.The displayed Read more

Beard hair

Beard hairs are usually thicker than hairs on the head: while the diameters of head hair range from 0.04 to 0.12 mm, the diameters of beard hair are on average twice as big: 0.09-0.23 mm.However, the structure of beard Read more
