High resolution image of early endosomes in which the membranes are easily seen as a tripartite track. Gold, labeling the C6 antigen, is observed only in the body of the early endosome and not in the ...

High resolution image of the macronucleus which contains microtubules that lie inside a seemingly intact nuclear envelope. Microtubules orient along the axis of macronuclear elongation in the form of ...

Longitudinal section through the buccal cavity of the oral region showing portions of 3 membranelles (1, 2 and 3): each membranelle consists of 3 rows of cilia. The oral ribs are seen on the right sid...

The undulating membrane is composed of two rows of basal bodies but only the outer row is ciliated. Both basal bodies are fully formed but only the ciliated member has an axosome and 9 + 2 axoneme. Th...

Immunogold labeled thin frozen section of P. multimicronucleatum. Gold lies over the microtubules of the basal bodies and the doublets of the cilia. Also short segments of the transverse and postcili...

The cytosol of Paramecium contains many vesicles of various sizes, shapes and contents as well as complex particles such as ribosomes and glycogen granules. The rough endoplasmic reticulum exists as m...

Immunogold b-tubulin labeled ribbons that extend from the cytopharynx and have discoidal vesicles bound to their kinetic side, i.e., their anterior side relative to the cell’s longitudinal axis (sid...

Immunogold labeled microtubules next to the cytoproct radiate from basal bodies and also from the tip of the cytoproct. These microtubules lie along the approaching spent DV. b-tubulin immunogold labe...

The radial arms of the Contractile Vacuole Complex or CVC each contain a collecting canal enclosed by a microtubular ribbon split lengthwise into several smaller ribbons, a meshwork of smooth spongiom...
