Mitochondria of Vorticella convallaria like other ciliates, have tubular cristae arising from their inner membranes. However, they also have a bundle of filaments (DNA?) that extend through the center of the organelle. TEM taken on 4/5/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg 17,150X. The raw negative was scanned with an Epson Perfection V750 Pro and this high resolution image is best used for quantitative analysis.
