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...

Early transmission electron micrograph of a thin section of a secretory cell from guinea pig pancreas illustrating vesicle trafficking between the rough endoplasmic reticulum and Golgi apparatus (uppe...

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...

Higher magnification view of the spongiome of the Contractile Vacuole Complex. The spongiome is composed of a three dimensional array of tubules that are continuous with the CV membrane. Many tubules ...

A rare micrograph of the contractile vacuole and intact contractile vacuole pore membrane of Euplotes. Close examination at high magnification reveals the organization of microtubules lining the pore ...

The 11 micrographs of the group are views of a serially-sectioned contracted Vorticella convallaria cell that show the main features of this cell. This figure shows 1 food vacuole; micronucleus; contr...

The decorated spongiome of the CVC is composed of 50nm tubules that have a pattern of helically wound subunits attached to their cytosolic surfaces. These tubules can be up to one micrometer or more i...

A view of the E-face of the fractured collecting canal of the contractile vacuole showing its association with microtubular ribbons and with the smooth spongiome. The E-fracture face of the smooth spo...

The contractile vacuole pore is coated on its cytosolic side by helically wound microtubules. Other microtubules abut this helix and extend out to the surface of the contractile vacuole where they are...
