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...

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 the edge of last food vacuole in se...

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...

The contractile vacuole of V. convallaria empties into a convoluted chamber. This chamber is covered by the alveoli and plasma membrane of the pellicle and is open to the cell’s surface via the peri...

The contractile vacuole pore is encircled on its cytosolic surface with microtubules. Other microtubules arise from these encircling microtubules and extend far out into the cell where they provide st...

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...

This EM features the striated bands that link the membranes under the surface depressions of the cortex. The bands insert into the epiplasm, and in this case, they separate to pass around the parasoma...

Quick-freeze deep-etch image of two decorated tubules with helically wound subunits on their cytosolic surfaces. Each step in a helical turn appears to be formed of three dyads lying side by side acro...
