Squash preparation of  onion root tip cells stained to reveal chromosomes,  Bright field illumination, light microscopy.  This image was taken with the X40 objective lens.  Depth of focus is extremely low at this magnification.  Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced.  The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.

Pathogen yeasts infections are treated with fluconazole, that blocks the lanosterol 14-alpha demethylase. This enzyme is essential for the biosynthesis of ergosterol, that is essential for the permeability and rigidity of the fungal plasma membrane. The magnification shows the active site with fluconazole interacting with a heme group. Source PDB entry 5esf.
