Halteria grandinella is a fresh water oligotrich ciliate. It lacks long rows of somatic cilia called kineties but has a few somatic ciliary bristles as well as a well developed oral and adoral or peri...

High resolution view of the cytoproct ridge at higher magnification. The unique system of thick fibers extends from each side of the ridge toward the center of the ridge. These thickened fibers are no...

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...

Immuno-gold labeling of corn stunt spiroplasma (CSS, Spiroplasma kunkelii, Class Mollicutes) in sieve elements and other phloem cells of infected maize root tissue. In this image, CSS appears to be cr...

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...

A high resolution image of a cell actively undergoing endocytosis that develops an extensive layer of vesicles and cisternae composed for the most part of smooth undecorated membrane. The uncoated cis...

High resolution image of a cell treated with trifluoperizine (TFP), all stages of endocytosis and movement to the early endosomes and out of the early endosomes can be found. These steps begin at the ...

This image shows a dikinetid which is set in a shallow basin in the cell surface. The pair of basal bodies have a proximal cartwheel and a dense septum (not found in most bbs) just distal to the cartw...

A tangential view through a dikinetid shows two microtubular ribbons extending toward the pellicle, one from each basal body, and how they overlap with ribbons from other basal bodies under the pellic...

Transmission electron micrograph of Drosophila nephrocyte garland cell from ema[1] mutant. ema mutant garland cells are filled with very large electron-lucent alpha and electron-dense alpha and beta ...
