Transmission electron micrograph of section through the macronucleus of Nassula sp containing many darkly staining nucleoli.

At this level of the buccal cavity the opening into the cytopharynx is not seen. Pharyngeal vesicles accumulate at the ends of the cytopharyngeal lamellae and are present under the basal bodies of the...

High resolution image of the somatic basal bodies along the sides of the cytoproct ridge have bundles of microtubules extending into the endoplasm from near their proximal ends. These bundles make con...

High resolution image of quick-freeze deep-etch rotary-shadowed replica of an early endosome with two clathrin-coated evaginations. Presumably these coated pits contain receptors for cargo that will b...

High resolution view of an early endosome with at least two coated evaginations showing, lies next to the proximal end of a fractured basal body. Other clathrin cages may indicate other evaginations f...

An image of the base of a dikinetid deeper in the cell. A postciliary ribbon and other microtubules fan out from it's basal bodies. TEM taken on 6/3/69 by R. Allen with Philips 300 operating at 60kV. ...

The somatic basal bodies along the sides of the cytoproct ridge have bundles of microtubules extending into the endoplasm from near their proximal ends. These bundles make contact with the spent vacuo...

Mucocysts have a herringbone pattern of subunits and are surrounded by a membrane that fuses with the plasma membrane. When the mucocyst content is extruded the content expands (see Hausmann, Protisto...

A view of the cortex showing early endosomes are often cup shaped and can have several coated evaginations arising from the rim of the cup. TEM taken on 8/10/65 by R. Allen with RCA EMU3F operating at...

Polykinetids of one membranelle of the buccal cavity, probably membranelle 1. Accessory microtubules arise from the row of basal bodies on one side. Parasomal sacs are not seen associated with this me...
