The 11 micrographs of the group are views of a serially-sectioned contracted Vorticella convallaria cell that show the main features of this cell. This figure shows 3 food vacuoles; 2 segments of the macronucleus; micronucleus; perioral cilia; tips of “ribbed wall” along adoral side of the peristome that contain the lamellae; paroral cilia; contractile vacuole; tube or chamber containing bacteria linking the contractile vacuole to the peristome; and myonemes linking the perioral zone to the cell’s lateral pellicle. TEM taken on 4/1/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 2,150X. Bar = 2?m. The negative was printed to paper and the image was scanned to Photoshop. This image is suitable for qualitative analysis. A high resolution version of this image in the library (CIL:40626) is available for quantitative analysis.
