An image of the transition from basal bodies to cilia within a portion of one of the oral membranelles of Euplotes. Parasomal sacs occur between the rows of basal bodies although these endocytic ports are not as evident in Euplotes as in other ciliates. 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 7/29/67 by R. Allen with Philips 200 operating at 60kV. Neg. 28,000X. Bar = 0.2?m. A print of the negative was scanned and processed in Photoshop. This image is best used for qualitative analysis. A high resolution image (CIL:9706) is available for quantitative analysis.
