Cross fracture of cilia of the quadrulus. The basal body/cilium complexes are a little less tightly packed than in the peniculus. There are four or five rows of parasomal sacs interspersed with basal...

High resolution image of vesicles and early endosomes under the membranelles of the peniculus of the buccal cavity. Cilia and basal bodies are tangentially fractured in this quick-freeze deep-etch pre...

High resolution detail of cytopharyngeal vesicles. TEM taken on 3/2/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 19,500X. The raw film was scanned with an Epson Perfection V750 Pro. This ...

At the cytopharynx the acidosomes come in contact with the carrier vesicles that are derived from early endosomes. These carrier vesicles bind to the microtubular ribbons as do the acidosomes. The car...

A bundle of microtubules that arises from a basal body adjacent to the cytoproct comes to lie along a spent DV-IV. The assumption is that movement generated by molecular motors propels the spent vacuo...

The carrier vesicles dock with the acidosomes and then fuse with these larger vesicles before or as the vesicles dock at the nascent Digestive Vacuole. Thus the contents of the carrier vesicles are fi...

Detail of cytopharyngeal vesicles. TEM taken on 3/2/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 19,500X. Bar = 0.5µm. A print of the negative was scanned and processed in Photoshop. Th...

Secondary lysosomes contain a lumen in quick-freeze deep-etch (QF-DE) images resembling etched matrix proteins rather than the honeycomb appearance of acidosomes. Lysosomes often have one or more para...
