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...

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...

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...

An electron micrograph of a potion of a cell of the unicellular alga Chlamydomonas reinhardii illustrating the eye spot, an organelle found inside the chloroplast that is composed of red carotenoid pi...

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...

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...
