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. The raw negative was scanned with an Epson Perfection V750 Pro and this high resolution image is best used for quantitative analysis.
