High resolution image of quick-freeze deep-etch of the P-face of the contractile vacuole. This face has many IMPs that are presumably transmembrane proteins many of which have been pulled free of the ...

Quick-freeze deep-etch of the P-face of the contractile vacuole. This face has many IMPs that are presumably transmembrane proteins many of which have been pulled free of the leaflet. There are also p...

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...

A high resolution view of a median longitudinal section through this collecting canal that may be artificially swollen at two sites where it is encircled by structural microtubules. Smooth spongiome ...

A high resolution micrograph of the collecting canal of the contractile vacuole surrounded by smooth spongiome remnants and decorated tubules of the CVC. Microtubules bordering the flattened collectin...

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...

A median longitudinal section through this collecting canal that may be artificially swollen at two sites where it is encircled by structural microtubules. Smooth spongiome forms a mesh around the co...

DVD quality video of the Contractile Vacuole Complex of Paramecium multimicronucleatum. In vitro CVC rounding/relaxing cycles. An in vitro CV in a ruptured Paramecium cell is surrounded by cytoplasmic...
