V. convallaria preserved in collidine buffered fixative (not cacodylate) has a less dense cytoplasm in which oranelles are easier to recognize. The rough ER has vesiculated but this vesiculation enhan...

Opercularia coarctata. Transmission electron micrograph of contracted cell body. This ciliate does not have rows of basal body/cilia over its whole surface but has cilia in the oral region and in a tr...

A contractile vacuole in systole. The CV has collapsed into vesicles and tubules. Three CV pores can be seen where the CV meets the pellicle. Smooth membrane cisterna surrounds some cytoplasm, possibl...

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 high resolution image of the pellicle of Didinium, in cross section of a non-dividing cell, has a plasma membrane with a distinct glycocalyx on its external surface and a flattened alveolar sac syst...

The flagellar pocket of a Trypanosoma brucei bloodstream form cell, with short flagellum. The image shows a new flagellum starting to grow from the flagellar pocket, in preparation for the next cell d...

The division furrow of a dividing Didinium. A thick layer of epiplasm coated on the cytosolic side by mitochondria forms the constricting ring in the furrow. As usual mucocysts lie between the epiplas...

Localization of Alexa Fluor-594-α-factor-labeled endosomes (red), Abp1-GFP- (green) and Abp140-3GFP- (green) labeled endocytic vesicles. It was possible to distinguish endocytic vesicles from actin c...

This high resolution EM features the striated bands that link the membranes under the surface depressions of the cortex. The bands insert into the epiplasm, and in this case, they separate to pass aro...

A composite of cross sections through the cilium-basal body complex extending from the cilium to the transition zone between the cilium and basal body and ending at the proximal tip of the basal body....
