A relatively low magnification view of the anterior end of Paramecium showing the placement and size of trichocysts relative to the cortex and cytoplasmic organelles. Trichocysts docked at the crests ...

In addition to plates the plasma membrane contains IMPs on its P-fracture face in ring or parenthesis shape at sites of trichocyst secretion. A ring actually consists of two circles of IMPs and signif...

A high resolution image of a tangential section through the cell’s surface show the pairs of basal bodies in cross section. The ends of kinetodesmal fibers point anteriorly in the cell, the postcili...

High resolution image of microtubules that sometimes extend deep into the cytosol from the basal bodies. They serve to guide the trichocysts to their docking sites at the plasma membrane (see Plattner...

b-tubulin immunogold labeled microtubules arise from the apex of the cytoproct ridge and pass to the spent DV membrane. Trichocyst and trichocyst tip included in this image. TEM taken on 7/5/96 by R. ...

A high resolution image of the cortex of Paramecium consists of a plasma membrane and alveolar sacs, with their inner and outer alveolar membranes that limit the area in which endocytosis can easily o...

Cross sections of basal bodies at the level of their attachments to the kinetodesmal fiber, the anterior basal body is attached by a thin bridge. The proximal ends of one postciliary microtubular ribb...

Paramecium caudatum is a peniculine oligohymenophoran ciliate that has numerous rows of cilia called kineties that run along the posterior to the anterior axis on the cell’s dorsal side but curve ar...
