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. Bar = 2?m.
Biological Process: Oral apparatus organization, Microtubule bundle formation, Bacterial symbiont interaction
A print of the negative was scanned and processed in Photoshop. This image is best used for qualitative analysis. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm. There is a high resolution version of this image in the library (CIL:39128) which is available for quantitative analysis. Additional information available at (http://www5.pbrc.hawaii.edu/allen/).
