High resolution micrograph through an oblique section of the cortex of Coleps showing many ribosomes, ordered into whorls and spirals, collectively called polysomes, on the surface of the rough endopl...

A high resolution image of a bundle of microtubules supporting the oral apparatus of Coleps. This micrograph shows the detail of microtubular cross-bridging within one of these rods. Microfibrillar br...

High resolution image of the macronucleus of Coleps hirtus. Heterochromatin and nucleoli are seen as smaller and larger stained bodies, respectively, in the macronucleus. Many nuclear pores exist in t...

A high resolution image of the surface of Coleps hirtus. Alveoli have longitudinal margins along the ciliary rows as well as lateral margins spaced at intervals of one or two basal bodies along the ro...

Bundles of microtubules which compose rods that exhibit periodicity along their individual microtubules. Discoidal vesicles seem to be bound to the rod surfaces. The bundles of filaments penetrate int...

A view near the oral apparatus of Coleps and the attachment site of a microtubule filament bundle, fibrous interconnections, and a rod near a basal body that is out of the section plane in this TEM. D...

Longitudinal section of somatic cilia showing the axoneme, basal body, and attached fibrous and microtubular elements. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alco...

A high resolution of an oblique section of the Coleps contractile vacuole pore revealing the supporting microtubules and adjacent fibrous layer. Standard glutaraldehyde fixation followed by osmium tet...

A high resolution image of a cortical monokinetid showing the basal body as well as postciliary and transverse microtubular ribbons. Slender endosomal vesicles accumulate near the bottom of a parasoma...

Surface of Coleps hirtus. Alveoli have longitudinal margins along the ciliary rows as well as lateral margins spaced at intervals of one or two basal bodies along the rows. Margins of adjacent alveoli...
