The cilia of a membranelle of the AZM (adoral zone of membranelles) have well defined doublets, singlets and dynein arms as well as spokes. Euplotes has a plasma membrane which covers a very flat and electron opaque alveolar sac. The alveolar sac membrane appears less opaque than the alveolar content. The septum between alveoli forms a slight bulge in the cell surface. 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 5/24/69 by R. Allen with Philips 200 operating at 60kV. Neg. 28,000X. A print of the negative was scanned and processed in Photoshop. This image is best used for qualitative analysis. A high resolution image (CIL:9705) is available for quantitative analysis.
