A high magnification view of the tubulated CV membrane attached to ampullae 2, 3, 4 and 5 of the CVC. The tubules lie against the ribbon of microtubules as well as form a large mat lying inward (centr...

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...

Overview of Coleps hirtus cell seen in this median transverse section. This barrel-shaped cell has a few rows of cilia and the cell is covered with calcified polysaccharide platelets that are housed w...

Halteria grandinella is a fresh water oligotrich ciliate. It lacks long rows of somatic cilia called kineties but has a few somatic ciliary bristles as well as a well developed oral and adoral or peri...

High resolution image of a longitudinal section through one of the radial arms of the contractile vacuole complex displaying two rows of openings from the smooth spongiome into the collecting canal. T...

Collecting canal of the contractile vacuole complex. Normally the collecting canal is expanded when the CV is in systole. In this micrograph the collecting canal is empty so that its two sides are fla...

A contractile vacuole in systole. The CV has collapsed into vesicles and tubules. Three CV pores can be seen where the CV meets the pellicle. Smooth membrane cisterna surrounds some cytoplasm, possibl...

Vesicles and early endosomes under the membranelles of the peniculus of the buccal cavity. Cilia and basal bodies are tangentially fractured in this quick-freeze deep-etch preparation. Preendosomal ve...

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...
