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 microtubular ribbon which has now d...

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...

High resolution image of the CVC complex. The membrane along the collecting canal of ruptured cells shows that the excess smooth spongiome membrane forms a three-dimensional array similar to etiolated...

An electron micrograph of a thin frozen section treated with a clone of the mAb (D40-2) used to show the A4 antigen on decorated tubules. The immunogold lies along the outer margin of these tubules fo...

High resolution image of quick-freeze deep-etch of the P-face of the contractile vacuole. This face has many IMPs that are presumably transmembrane proteins many of which have been pulled free of the ...

Quick-freeze deep-etch of the P-face of the contractile vacuole. This face has many IMPs that are presumably transmembrane proteins many of which have been pulled free of the leaflet. There are also p...

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...

The radial arms of the Contractile Vacuole Complex or CVC each contain a collecting canal enclosed by a microtubular ribbon split lengthwise into several smaller ribbons, a meshwork of smooth spongiom...

The membrane along the collecting canal of ruptured cells shows that the excess smooth spongiome membrane forms a three-dimensional array similar to etiolated chloroplasts when a piece of wood stays o...

A partially filled contractile vacuole is connected to two regions of spongiome tubules. The extra CV membrane is acquired from these spongiomes. Presumably some of these spongiome tubules are decorat...
