This micrograph through an oblique section of the cortex of Coleps shows many ribosomes ordered into whorls and spirals, collectively called polysomes, on the surface of the rough endoplasmic reticulu...

Some tubules near a contractile vacuole which appear to be decorated with pegs similar to the spongiome of the CV of Paramecium. In Paramecium these pegs are known to be V-type proton pumps (V-ATPases...

Section through the cytopharynx of Coleps showing the corrugated lips containing lamellae surrounding the atrium of the buccal cavity. Rods composed of hexagonally packed microtubules that support the...

A longitudinal section of somatic cilia of Coleps showing the axoneme, basal body, and attached fibrous and microtubular elements. Adjacent digestive vacuoles and cortical cytoplasm evident with typic...

High resolution image of typical cytoplasm of Coleps hirtus. The cytosol contains rough ER, mitochondria with tubular cristae, peroxisomes, early endosomes, and bacterial endosymbionts. Small and larg...

Cross section of a Coleps cilium showing the axoneme consisting of 9 doublet and 2 central microtubules. Doublets have a complete A subfiber and an attached B subfiber. Two dynein arms, outer and inne...

The monokinetids (single somatic basal bodies) of Coleps hirtus bear an anteriorly directed striated fibrous kinetodesmal fiber and a posteriorly directed ribbon of postciliary microtubules that arise...

This high resolution micrograph may show important features involved in calcareous plate formation within the alveoli that underlie the plasma membrane in Coleps. Densities are seen on the inner alveo...

An image image of the multiple membrane systems at the cortex of ciliates. Thickened alveolar densities partially coat the alveolar membrane within the alveoli which underlie the plasma membrane of ci...

A high resolution micrograph of the monokinetids (single somatic basal bodies) of Coleps hirtus bear an anteriorly directed striated fibrous kinetodesmal fiber and a posteriorly directed ribbon of pos...
