Some tubules near a contractile vacuole which appear to be decorated with pegs similar to the spongiome of the CV of Paramecium. In Paramecium these pegs are known to be V-type proton pumps (V-ATPases...

High resolution micrograph of cubic membrane array which represents the cell’s method of storing large quantities of lipid and protein bilayers into the smallest possible volume. These membranes can...

Quick-freeze deep-etch of the contractile vacuole E-fracture face. This face like the collecting canal membrane is porous indicating that many IMPs have been removed from this leaflet during fracturin...

A collecting canal of the contractile vacuole surrounded by smooth spongiome remnants and decorated tubules of the CVC. Microtubules bordering the flattened collecting canal are labeled with immunogol...

A high resolution of some tubules near a contractile vacuole that appear to be decorated with pegs similar to the spongiome of the CV of Paramecium. In Paramecium these pegs are known to be V-type pro...

Contractile vacuole of Nassula sp. Parts of the single CV appear on two sides of the CV pore. Fields of spongiome abut the filled portions of the CV. TEM taken on 3/27/69 by R. Allen with Philips 300 ...

A high resolution image and rare micrograph of the contractile vacuole and intact contractile vacuole membrane of Euplotes. Close examination at high magnification reveals the organization of microtub...

The contractile vacuole may evacuate through a CV pore located in an indentation of the pellicle not far from the adoral end. TEM taken on 3/18/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg...

The contractile vacuole, an organelle used by many protists for osmoregulation of water and some ions, such as calcium, is connected to the cell surface in Tetrahymena usually by two “pores," indent...
