This figure shows the connection between the peristome and the food vacuole forming zone where the alveoli end. The cytostome is the opening that connects these two zones. TEM taken on 6/13/69 by R. Allen with Philips 300 operating at 60kV. Neg. 6,370X. Bar = 1µm. A print of the negative was scanned and processed in Photoshop. The raw negative was scanned with an Epson Perfection V750 Pro and this high resolution image is best used for quantitative analysis.
