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...

High resolution view of the bundles of microtubules that arise from along the elaborately woven blanket of the filamentous reticulum that covers the ribbed wall of the right side of the buccal cavity....

High resolution image of the dividing macronucleus shows it may be porous to microtubules. Segments of microtubules are found both outside and inside the nuclear envelope in this figure although one c...

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

This micrograph shows the pegs on the surface of the decorated tubules associated with the contractile vacuole that are negatively stained by the uranyl acetate dissolved in the methylcellulose soluti...
