11 micrographs are views of a serially-sectioned contracted Vorticella convallaria cell that show the main features of this cell. This figure shows 3 food vacuoles (of a total of about 15 in the cell) containing bacteria and part of a trochal band of basal bodies that surrounds the aboral scopular zone where the stalk originates. TEM taken on 4/2/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 3,150X. 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:39327) which is available for quantitative analysis.
