An image showing the mitochondria packed with tubular cristae and the cytosol contains a jumble of microtubules. Basal bodies of the somatic kineties appear as dikinetids with a ribbon of transverse microtubules arising from the anterior basal body. The cytosol near the basal bodies is filled with ribosomes while dense rosettes of glycogen are found at the level of the mitochondria. TEM taken on 8/3/67 by R. Allen with Philips 200 operating at 60kV. Neg. 19,200X. Bar = 0.2µm. A print of the negative was scanned and processed in Photoshop. This image is best used for qualitative analysis. A high resolution image (CIL:9703) is available for quantitative analysis. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm. Additional information is available at (
