High resolution image of Colpoda. A soil ciliate and this micrograph is characterized by numerous mucocysts and food vacuoles containing bacteria in various stages of digestion. This electron microgra...

11 micrographs are views of a serially-sectioned contracted Vorticella convallaria cell that show the main features of this cell. This figure shows 3 food vacuoles (of a total of about 15 in the cell...

High resolution image of Halteria fixed in cacodylate-buffered fixative and stained. The round, dark bodies, possibly pigment granules, which were transparent in other preparations are electron-opaque...

Food vacuole and macronucleus of Didinium. The food vacuole contains unexploded trichocysts of Paramecium. Further details available at Wessenberg, H. and Antipa, G. 1968. Studies on Didinium nasutum....

A low power view of a median transverse section of a green Trichodina that lives on the surface of a freshwater snail collected in central Illinois. In this view the abundant endosymbiotic zoochlorell...

High resolution image of longitudinal section of somatic cilia showing the axoneme, basal body, and attached fibrous and microtubular elements. Adjacent digestive vacuoles and cortical cytoplasm evide...

The postoral microtubular bundles form a track along which a newly released food vacuole rapidly migrates to the cell’s posterior end. Here the flattened cytopharyngeal membrane lies next to these b...

Conventional freeze-fractured images of DV-III membrane also suggests a transformation from a membrane with a smooth E-fracture face to one with characteristic large IMPs on its E-fracture face. The D...

Accumulation of golgi cupulas near a food vacuole. The food vacuole shown has already fused with many vesicles that have already added their membrane as well as their dense inner lining to the vacuole...

High resolution image of cilia and cytopharyngeal vesicles containing a flocculent content of unknown composition which lie next to the cytopharynx and between the buccal cavity and what may be the n...
