A high resolution image of the cilia of a membranelle of the AZM (adoral zone of membranelles) have well defined doublets, singlets and dynein arms as well as spokes. Euplotes has a plasma membrane wh...

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...

High resolution image of early endosomes in which the membranes are easily seen as a tripartite track. Gold, labeling the C6 antigen, is observed only in the body of the early endosome and not in the ...

This is one of six images in Figure 6 in Apaja et al., JCB 2010 that shows the fate of various model membrane proteins, that are either folded or in the unfolded state at the plasma membrane, expresse...

This high resolution micrograph may show important features involved in calcareous plate formation within the alveoli that underlie the plasma membrane in Coleps. Densities are seen on the inner alveo...

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...

This freeze fracture view of the pellicle of V. microstoma near the aboral end of the zooid shows the region where the width of each circumferential alveolus is narrower and thus the strings of fractu...
