A high resolution image of the mitochondria packed with tubular cristae and the cytosol contains a jumble of microtubules. Basal bodies of the somatic kineties appear as dikinetids with a ribbon of t...

An 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 system. Under the a...

The division furrow of a dividing Didinium. A thick layer of epiplasm coated on the cytosolic side by mitochondria forms the constricting ring in the furrow. As usual mucocysts lie between the epiplas...

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...

Another view of the cytopharynx but in a dividing Didinium. This cytopharynx is in the proter (anterior) daughter cell. The lamellae, each consisting of a set of perpendicularly arranged microtubules ...

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 ...

High resolution image of microtubules that 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...

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...

An image showing the mitochondria packed with tubular cristae and the cytosol contains a jumble of microtubules. Basal bodies of the somatic kineties appear as dikinetids with a ribbon of transverse m...
