Immunogold labeled thin frozen section of P. multimicronucleatum. Gold lies over the microtubules of the basal bodies and the doublets of the cilia. Also short segments of the transverse and postcili...

A bundle of microtubules that arises from a basal body adjacent to the cytoproct comes to lie along a spent DV-IV. The assumption is that movement generated by molecular motors propels the spent vacuo...

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...

A grazing section through the cell’s surface shows segments of six rows of cilia running across the figure sectioned superfically at the top and deeper into the cell as one progresses down the figur...

The figure shows the beginning of the cytopharyngeal ribs of the ribbed wall. The peristome is bordered on one side by the paroral kinety that has 2 rows of basal bodies, of which only one is ciliated...

A glancing view of the thigmotactic ciliature of Conchophthirus reveals details of cortical structure. CIL:39230 is a near serial section. Both exhibit the characteristic zig-zag kinetal arrangement o...

A glancing view of the cortex of Conchophthirus reveals details of cortical structure. This includes the nature of the cell membrane and the alveolar membranes that reside immediately below the surfac...

A glancing view of the cortex of Conchophthirus reveals details of cortical structure. A near serial section with CIL:39232. This includes the nature of the cell membrane and the alveolar membranes th...

The cytosol of Paramecium contains many vesicles of various sizes, shapes and contents as well as complex particles such as ribosomes and glycogen granules. The rough endoplasmic reticulum exists as m...
