Description

High resolution of bundles of microtubules which compose rods that exhibit periodicity along their individual microtubules. Discoidal vesicles seem to be bound to the rod surfaces. The bundles of filaments penetrate into the food vacuole forming a zone from the bases of the basal bodies. Symbiotic bacterium, mitochondrion, and mucocysts are seen. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness. TEM taken on 5/22/69 by R. Allen with Philips 300 operating at 60kV. Neg. 14,800X. The raw film was scanned with a Nikon Coolscan 9000ED. This high resolution image is suitable for quantitative analysis. Additional information available at (http://www5.pbrc.hawaii.edu/allen/).
