A higher magnification view that shows the bilayer nature of the ciliary membrane, plasma membrane and the outer and inner (alveolar sac membranes of the alveoli. The 9-doublet + 2-singlet microtubula...

This high resolution micrograph of Paramecium multimicronucleatum is adapted with permission from Fig. 1 in J. Cell Biol. 49:1-20, 1971. Paramecium is covered with cilia which arise from regular surfa...

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...

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...

Quick-freeze deep-etch images show a more three dimensional view of acidosomes surrounding a phagosome. Acidosomes are unique in that they contain indentations of their membrane. The lumen has a honey...

Planar view of the cortex demonstrating that the striated bands do indeed link the internal slopes of one cortical unit with all surrounding units. Parasomal sacs lie to the side of a single basal bod...

A high resolution of a quick-freeze deep-etch rotary shadowed replica of a parasomal sac from which a clathrin-coated preendosomal vesicle has pinched off. The typical clathrin cage structure is prese...

Paramecium multimicronucleatum is covered with cilia which cilia arise from regular surface depressions roughly rectangular in shape. This image is adapted with permission from Fig. 1 in J. Cell Biol....

In one experiment in which electric shock was applied to Paramecium cells to trigger trichocyst discharge the macronucleus in one cell was observed to undergo morphological changes of two types. First...
