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...

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 ...

Contractile vacuole in the opisthe of a dividing cell. This is presumably the mature CV of the original “mother” cell. Spongiome tubules form large regions of additional membrane on two sides of t...

Accumulation of golgi cupulas near a food vacuole. The food vacuole shown has already fused with many vesicles that have already added their membrane as well as their dense inner lining to the vacuole...

Transmission electron micrograph of an unbudded yeast cell in which vacuole fission and fusion are apparent. A mitochondrion is faintly discernible above and slightly to the right of the nucleus. A si...

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...

Transmission electron micrograph of a polygonal vacuole from an untreated vma9 mutant cell. The vacuole contains a concentric multilamellar body. (40,000X). This image is part of a group of yeast vac...

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; a segment of the ma...
