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...

An 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 nascent food v...

A layer of mucocysts is docked under the pellicle. The pellicle has a plasma membrane and an alveolar sac system. Both basal bodies of a dikinetid are ciliated, and the food vacuoles are plentiful and...

This image of Halteria was fixed in cacodylate-buffered fixative and stained. The round, dark bodies, possibly pigment granules, were transparent in other preparations are electron-opaque following th...

High resolution image of Halteria showing the extension of buccal cavity and the cytopharynx passing into the cell. Vesicles accumulate at the cytopharynx next to the lamellae. These vesicles may be h...

Stacks of rough endoplasmic reticulum (ER) cisternae seen in a transmission electron micrograph of a section through a secretory acinar cell from the bat exocrine pancreas. The rough ER is here involv...

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...

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

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