Microtubules sometimes extend deep into the cytosol from the basal bodies. They serve to guide the trichocysts to their docking sites at the plasma membrane (see Plattner, Westphal and Tiggemann, J. C...

A high resolution image of a cell actively undergoing endocytosis that develops an extensive layer of vesicles and cisternae composed for the most part of smooth undecorated membrane. The uncoated cis...

High resolution image of a cell treated with trifluoperizine (TFP), all stages of endocytosis and movement to the early endosomes and out of the early endosomes can be found. These steps begin at the ...

A tangential view through a dikinetid shows two microtubular ribbons extending toward the pellicle, one from each basal body, and how they overlap with ribbons from other basal bodies under the pellic...

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 postciliary microtubular ribb...

In a cell treated with trifluoperizine (TFP), all stages of endocytosis and movement to the early endosomes and out of the early endosomes can be found. These steps begin at the parasomal sac and endi...

Ancistrum is a marine ciliate that inhabits the mantle cavity of mytiliid mussels. This image shows a good view of the macronucleus, mitochondria with tubular cristae, and what are probably flask-shap...

A view of the entry to the oral apparatus of the green Trichodina that lives on the surface of a freshwater snail collected in central Illinois. In this view the haplokinety and the polykinety of the ...

11 micrographs of views of a serially-sectioned contracted Vorticella convallaria cell that show the main features of this cell. This figure shows 5 food vacuoles and the edges of 2 more. The connecti...

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...
