A glancing view of the thigmotactic ciliature of Conchophthirus reveals details of cortical structure. CIL:39231 is a near serial section. Both exhibit the characteristic zig-zag kinetal arrangement o...

The 11 micrographs of the group are views of a serially-sectioned contracted Vorticella convallaria cell that show the main features of this cell. This figure shows 1 food vacuole; micronucleus; contr...

The 11 micrographs of the group are views of a serially-sectioned contracted Vorticella convallaria cell that show the main features of this cell. This figure shows the edge of last food vacuole in se...

The 11 micrographs of the group are views of a serially-sectioned contracted Vorticella convallaria cell that show the main features of this cell. This figure shows 3 food vacuoles; 2 segments of the ...

A high resolution micrograph of the proximal ends of the basal bodies of a cirrus of Euplotes. the basal bodies are embedded in a perforated plate of electron opaque material. Microtubules arise from ...

A view of cross-sectioned rows of basal bodies in Nassula exposing the absence of cilia. Only a few basal bodies may have attached cilia as seen by the few cilia present in the upper right row. Basal ...

High resolution image of cross sections of basal bodies at the level of their attachments to the kinetodesmal fiber, the anterior basal body is attached by a thin bridge. The proximal ends of one post...

A high resolution micrograph of the transverse microtubular ribbon, consisting of ~3 microtubules, extends to the cell's left of the basal body and rises to the top of the ridge where it ends. Thus th...

A dividing Didinium nasutum. This large ciliate is capable of engulfing Paramecium. It has a thick ectoplasm containing numerous mucocysts embedded in its extensive epiplasm. Its external surface is c...

P. multimicronucleatum in defecation. When a spent vacuole has fused with the single membrane along the midline of the ridge the lips of the cytoproct split apart and form a wide gap. The membrane of ...
