Dividing cells from the liquid endosperm of the lily Haemanthus katherinae were fixed with paraformaldehye, embedded in epoxy, and 0.5 micrometer sections prepared. Images were obtained with the Wisconsin high voltage TEM at 1MEV. For this micrograph of a chromosome at prophase, the grid was tilted to 40 degrees. A similar micrograph tilted to 60 degrees is grouped with this image, making a stereo pair that provides an oblique 3D view.
