Description

11 micrographs are views of a serially-sectioned contracted Vorticella convallaria cell that show the main features of this cell. This figure shows 4 food vacuoles; 3 segments of macronucleus; cytopharynx open to peristome; cytostome or cell mouth; perioral cilia covered by folds of the pellicle and cortex. TEM taken on 4/5/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 2,150X. Bar = 2µm. The negative was printed to paper and the image was scanned to Photoshop. This digitized image is available for qualitative analysis. There is a high resolution version of this image in the library (CIL:39403) which is available for quantitative analysis. Additional information available at (http://www5.pbrc.hawaii.edu/allen/).

Technical Details

Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness. Additional information available at (http://www5.pbrc.hawaii.edu/allen/).
