Preparation of the live ciliate Tetrahymena pyriformis stained with a mitochondria-specific probe (Mitotracker green) and viewed with the CSU-10 confocal microscope. The mitochondria become visible a...

High resolution image of the cytoplasm of Tetrahymena. Mitochondria have tubular cristae, infoldings of their inner membranes. Peroxisomes, with a few tubular inclusions, mucocysts, and a planar view ...

High resolution view of the rough endoplasmic reticulum of Tetrahymena that sometimes forms large stacks or concentric circles from which other organelles are excluded. Peroxisomes lie nearby. EM take...

A view of the rough endoplasmic reticulum of Tetrahymena that sometimes forms large stacks or concentric circles from which other organelles are excluded. Peroxisomes lie nearby. EM taken on 6/21/67 b...

A view of early endosomes with coated evaginations at their margins. TEM taken on 8/15/67 by R. Allen with Philips 200 operating at 60kV. Neg. 19,200X. Bar = 0.5µm. The negative was printed to paper ...

A post ciliary microtubular ribbon extends from the proximal left side of the basal body and arches toward the cell surface where it ends near the longitudinal microtubular ribbon at the crest of the ...

The accessory microtubules at the proximal ends of the polykinetids, both in cross section and tangential section, are highlighted at higher magnification. This section shows one parasomal sac as well...

The new oral region in the opisthe starts to form as an unorganized field of new basal bodies develops at the equator of the cell surface. At first these do not resemble membranelles although some bas...

Up to three basal bodies have been seen in various stages of development near a mature basal body/cilium complex. In this micrograph 2 new basal bodies are present next to 2 cilia and 3 are forming ne...

The acidosome-like vesicle has a bull’s eye appearance with the invagination appearing in the middle of the vesicle. Other vesicles contain multiple layers resembling multilipid layers. Two vesicles...
