Cytopharyngeal basket in tangential section is composed of a complex of microtubular rods. The lumen of the basket contains many vesicles called cytopharyngeal vesicles. They may provide membrane for the nascent food vacuole, lysosomal and/or lytic enzymes, or all of these. Another role may be to provide vacuolar type ATPases (proton pumps) to the nascent food vacuole. TEM taken on 3/13/69 by R. Allen with Philips 300 operating at 60kV. Neg. 3,570X.
Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm. The raw negative was scanned with an Epson Perfection V750 Pro and this high resolution image is best used for quantitative analysis.
