The micronuclear separation spindle. Nuclear pores are not empty perforations but are closed by nonetchable material. The separation spindle must elongate as microtubules lengthen and/or slide against...

A view of the ER on which IMPs are organized into lines, arcs, and circles indicating organization of proteins within the ER membrane and possibly peripheral proteins attached to its cytosolic surface...

Tangential fractures through mature trichocysts. The planes in the paracrystalline stacks are exposed. The body is laced to the membrane but such associations must be severed when the trichocyst is di...

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...

Quick-freeze deep-etch image of a cytosolic region where trichocysts are developing. Vesicles, even small ones, contain contents that are compacting into paracrystalline form. These vesicles seem to h...

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...

Paramecium multimicronucleatum - Video of the Contractile Vacuole Complex. Activity of the two parts of a dissected CV. Division and subsequent fusion of an in vitro CV extruded from a ruptured Parame...

Paramecium multimicronucleatum - Video of the Contractile Vacuole Complex. Profile view of the rounding/relaxing of an in vitro CV. Side view of an in vitro CV of Paramecium spontaneously rounding and...

The cytopharyngeal ribbons of microtubules tend to curve into a “C” shape away from the cytopharynx but they still remain connected as a ribbon and are heavily labeled by immunogold when exposed t...
