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 ...

High resolution 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 ...

High resolution view of 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 thi...

High resolution quick-freeze deep-etch image of a fracture through the radial canal of the contractile vacuole. This technique presents a picture of a confusing array of non-etchable material surround...

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...

Quick-freeze deep-etch of an ampulla. The P-fracture face has numerous IMPs. The microtubular ribbon now forms two bands next to this ampulla. The ribbons will split into additional bands as they pass...

A circular depression on the dorsal surface of the cell marks the expulsion site of a contractile vacuole. This is referred to as the contractile vacuole “pore.". Microtubules encircle the pore. Tr...

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...

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...

High resolution image of when the antigen was visualized with immunogold using DS-1 on thin-frozen sections the antigen could be seen to be present on the periphery of the decorated tubules. The colle...
