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...

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 ...

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...

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 ...

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...

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...

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 ...

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 ...
