High resolution image of the cytoplasm of Tetrahymena. Mitochondria have tubular cristae, infoldings of their inner membranes. Peroxisomes, with a few tubular inclusions, mucocysts, and a planar view of rough ER, to which many polysomal ribosome arrays are attached, fill the cytosol. TEM taken on 2/11/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 19,500X. The raw film was scanned with an Epson Perfection V750 Pro. This image is best used for quantitative analysis.
Biological Process: Cytoplasm organization
Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness. Additional information available at (http://www5.pbrc.hawaii.edu/allen/).
