Detail of cytopharyngeal vesicles. TEM taken on 3/2/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 19,500X. Bar = 0.5µm. A print of the negative was scanned and processed in Photoshop. Th...

Contractile vacuole of Nassula sp. Parts of the single CV appear on two sides of the CV pore. Fields of spongiome abut the filled portions of the CV. TEM taken on 3/27/69 by R. Allen with Philips 300 ...

The transition from 3 to 2 rows of cilia can be seen in this view of the AZM. TEM taken on 7/24/67 by R. Allen with Philips 200 operating at 60kV. Neg. 1,370X. Bar = 5µm. Standard glutaraldehyde fix...

The membranelles of the AZM extending from the ventral side of the oral cavity are largely composed of 2 rows of cilia. A dikinetid of the somatic surface is also present. This dikinetid also has pigm...

A view of the AZM with basal bodies in longitudinal section and cilia sectioned lengthwise. Bunches of microtubules reside below the basal bodies and lie close to the cytopharyngeal vesicles. TEM take...

High resolution view of the E-face of the fractured collecting canal of the contractile vacuole showing its association with microtubular ribbons and with the smooth spongiome. The E-fracture face of ...

High resolution quick-freeze deep-etch image of a fracture through the radial canal of the contractile vacuole. This technique presents a picture of a confusing array of non-etchable material surround...

A high resolution image of a clump of at least seven small clathrin cages that are probably connected to an early endosome (below the fracture plane). The morphology of these cages shows a tighter pac...

A view of the E-face of the fractured collecting canal of the contractile vacuole showing its association with microtubular ribbons and with the smooth spongiome. The E-fracture face of the smooth spo...

Higher resolution of the area that shows the clathrin-coated cage near the peniculus and clathrin coated preendosomal and partially coated preendosomal vesicles. Early endosomes like the preendosomal ...
