Description

Quick-freeze deep-etch rotary-shadowed replica of a portion of the chemically-unfixed cytopharynx. The cytopharynx is continuous with the plasma membrane and is covered by only one membrane which is pleated over the ends of the cytopharyngeal microtubular ribbons. Numerous discoidal vesicles are bound single file along the anterior side only of each ribbon. This is the site where discoidal vesicles fuse with the cytopharyngeal membrane to form the digestive vacuole. TEM taken on 5/18/88 by C. Schroeder with Zeiss 10A operating at 80kV. Neg. 6,300X. Bar = 1µm. This image is suitable for qualitative analysis. There is a high resolution version of this image in the library (CIL:40510) which is available for quantitative analysis.
