Sections show the origin of one cytopharyngeal ribbon of 12 microtubules from the nodes and show the tight curve the ribbon follows over the cytostomal cord. These ribbons move discoidal vesicles, aci...

Single microtubules extend into the cytoplasm from the tips of the cytoproct ridge. These are thought to come to lie along the surface of the approaching DV-IV and to pull the ridge down against the D...

Structures at the left edge of the cytopharynx arise in contact with the filamentous reticulum that lies next to the alveoli to the side of the quadrulus. The cytopharyngeal ribbons coming out of the ...

The contractile vacuole pore is supported on its cytosolic side by a coil of microtubules and other microtubules extend from the pore to the CV membrane. The plasma membrane and CV membrane cover the ...

Sections show the origin of one cytopharyngeal ribbon of 12 microtubules from the nodes and show the tight curve the ribbon follows over the cytostomal cord. These ribbons move discoidal vesicles, aci...

The nascent digestive vacuole forms as the membrane of flattened vesicles fuse with the single membrane of the cytopharynx between the lamellae (2 microtubules forming a lamella) that are connected al...

The AZM enters the oral cavity of Euplotes where it occupies the right side of the buccal cavity while cytopharyngeal lamellae composed of microtubules arise from the left wall of the cavity. Large ve...

Up to three basal bodies have been seen in various stages of development near a mature basal body/cilium complex. In this micrograph 2 new basal bodies are present next to 2 cilia and 3 are forming ne...

The contractile vacuole of V. convallaria empties into a convoluted chamber. This chamber is covered by the alveoli and plasma membrane of the pellicle and is open to the cell’s surface via the peri...

A view of the right side of the cytopharynx showing the groove and its associated microtubules running longitudinally along the groove (for cross sections see Allen, J. Ultrastruct. Res. 63:64-78, 198...
