A micrograph showing the partially open cytoproct of Colpoda cucullus. The alveoli stop at the edges of the cytoproct and filamentous material (actin?) coats the inside of the single membrane that cov...

A high resolution image of the base of a dikinetid deeper in the cell. A postciliary ribbon and other microtubules fan out from it's basal bodies. TEM taken on 6/3/69 by R. Allen with Philips 300 oper...

An image of a dikinetid in cross section near its proximal end. A postciliary ribbon and a transverse ribbon are seen. A short kinetodesmal fiber buds from the side of the kinetid. Coated vesicles or ...

A cross section showing only one basal body in two different dikinetids. Cross sections of overlapping microtubular ribbons arising from the dikinetids are seen in the ridges next to the basal body. P...

A high resolution 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 ...

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...

Colpoda is a soil ciliate and this micrograph is characterized by numerous mucocysts and food vacuoles containing bacteria in various stages of digestion. This electron micrograph is near the posterio...

A high resolution image that 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 d...
