High resolution micrograph that shows the pegs on the surface of the decorated tubules that are negatively stained by the uranyl acetate dissolved in the methylcellulose solution used to give support ...

A partially filled contractile vacuole is connected to two regions of spongiome tubules. The extra CV membrane is acquired from these spongiomes. Presumably some of these spongiome tubules are decorat...

The collapsed cytopharyngeal membrane extends from the open cytopharynx into the cytosol. This membrane is associated with many docked acidosomes, vesicles that contain V-type proton translocating ATP...

The spongiome of membranes that surround the CV are probably not preserved in their native state when collidine buffered fixative is used. However, suggestions of decorated tubules as well as smooth t...
