Cytopharynx with numerous folded membrane ribs subtended by five or so microtubules. These microtubules have arms that bind to other microtubules and to the membrane of the cytopharynx and to surround...

High magnification view of the curved cytopharyngeal microtubular ribbons as they pass over the cytostomal cord. They carry the discoidal vesicles to their fusion sites at the cytopharyngeal membrane....

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 ...

The cytoproct is the cell’s defecation site where spent digestive vacuoles fuse with the plasma membrane. In this cell the cytoproct is closed and forms a ridge along the posterior suture on the ven...

The bottom of the buccal cavity is surrounded by specialized cytoplasm and contains a lip that constricts the opening leading through the cytostome into the receiving vacuole or nascent vacuole. The ...

Cytopharyngeal basket in tangential section is composed of a complex of microtubular rods. The lumen of the basket contains many vesicles called cytopharyngeal vesicles. They may provide membrane for ...

High resolution image of the cross section through a radial arm of the contractile vacuole complex. The collecting canal occupies the center of the arm whose membrane is supported by the radial microt...

A part of the CVC complex with some filled ampullae present. Masses of collapsed CV membrane are associated with the 11 microtubular ribbons. Ribbon 9 is curving away from the other ribbons and is ext...

The bottom of the buccal cavity is surrounded by specialized cytoplasm and contains a lip that constricts the opening leading through the cytostome into the receiving vacuole or nascent vacuole. The ...

At the base of the buccal cavity, which is surrounded by specialized cytoplasm, an oral rib lined passage opens through the cytostome to the single membrane lined cytopharynx which is corrugated by mi...
