A view of the cytopharynx and its nascent food vacuole forming region. The flattened pharyngeal vesicles that may contain monolayers or bilayers of lipids seem to be equivalent to the discoidal vesicl...

A contractile vacuole in systole. The CV has collapsed into vesicles and tubules. Three CV pores can be seen where the CV meets the pellicle. Smooth membrane cisterna surrounds some cytoplasm, possibl...

11 micrographs are views of a serially-sectioned contracted Vorticella convallaria cell that show the main features of this cell. This figure shows 5 food vacuoles; 3 segments of the macronucleus; per...

This view shows a transverse ridge cut with its sloping side lying tangentially in the section plane. The granulo-fibrillar filled peaks are prominent. Striated bands appear sectioned closer to their ...

The infraciliary lattice in this quick-freeze deep-etched image consists of a meshwork of branching fibers composed of many subfibers. Basal bodies and trichocyst tips extend through the openings of t...

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...

Conchophthirus was deciliated by calcium ion shock followed by shearing through a micropipette. This revealed the location of the deciliated basal bodies and the cell's surface architecture. In this i...

Higher resolution image of the surface of Nassula aurea. Early endosomes and clathrin coated vesicles. One clathrin coated pit at the bottom of a parasomal sac is shown. TEM taken on 2/22/71 by M. Aih...

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. ...

Image of a dikinetid of Euplotes shows the transverse microtubular ribbon as well as a postciliary ribbon extending from the posterior basal body. Vesicles containing electron opaque bodies are typica...
