P. multimicronucleatum in defecation. When a spent vacuole has fused with the single membrane along the midline of the ridge the lips of the cytoproct split apart and form a wide gap. The membrane of ...

A high resolution view of the radial arm of the Contractile Vacuole Complex or CVC each contain a collecting canal enclosed by a microtubular ribbon split lengthwise into several smaller ribbons, a me...

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...

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...

Quick-freeze deep-etch image of two decorated tubules with helically wound subunits on their cytosolic surfaces. Each step in a helical turn appears to be formed of three dyads lying side by side acro...

High resolution image of the 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 ...

Cell sectioned perpendicular to the surface. The parasomal sac ends internally as a coated pit, coated with clathrin. Where the coated pit has pinched off a clathrin-coated vesicle is formed. When the...
