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...

At this level of the buccal cavity the opening into the cytopharynx is not seen. Pharyngeal vesicles accumulate at the ends of the cytopharyngeal lamellae and are present under the basal bodies of the...

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...

High resolution view of the contractile vacuole pore encircled on its cytosolic surface with microtubules. Other microtubules arise from these encircling microtubules and extend far out into the cell ...

The contractile vacuole pore is encircled on its cytosolic surface with microtubules. Other microtubules arise from these encircling microtubules and extend far out into the cell where they provide st...

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 ...

A high resolution image of the pellicle of Didinium, in cross section of a non-dividing cell, has a plasma membrane with a distinct glycocalyx on its external surface and a flattened alveolar sac syst...

A high resolution image of a cortical monokinetid showing the basal body as well as postciliary and transverse microtubular ribbons. Slender endosomal vesicles accumulate near the bottom of a parasoma...
