A high resolution view of the Contractile Vacuole Complex. The CV membrane has collapsed into regularly spaced tubules oriented perpendicular to the microtubular ribbon in this ruptured cell. Some tub...

To determine what happens to the CV during systole we observed the CV in a living cell and then fixed the cell as soon as the CV had opened to the outside. It was apparent that the CV membrane does no...

A high resolution micrograph of the Contractile Vacuole Complex membrane system to determine what happens to the CV during systole we observed the CV in a living cell and then fixed the cell as soon a...

High resolution image of the decorated spongiome 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 microm...

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...

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...

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 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...
