QF-DE of a crystal whose P-fracture face shows many IMPs similar to the P-face of an acidosome lying nearby and trichocyst as well as trichocyst precursor vesicles. TEM taken by C. Schroeder on 6/3/8...

A high resolution image of portion of an isolated cilium exposing two rows of outer dynein arms arising from subfiber A of each doublet. The heavy chains of the dynein complex are linked to the microt...

High resolution image of an isolated and longitudinally fractured cilium exposing the middle of the cilium. The spokes extend from the doublets toward the two singlet microtubules. These spokes are sp...

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 view of quick-freeze deep-etch of the contractile vacuole E-fracture face. This face, like the collecting canal membrane, is porous indicating that many IMPs have been removed from thi...

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...

Thin section of Prochloron, a photosynthetic prokaryote showing adpressed thylakoid membranes. This image group includes freeze-fracture images showing the particle sizes and distribution on the thyla...

A segment of the edge of the axoneme showing the outer axonemal dynein arms that extend from the A-subfiber of a doublet to bind to the B subfiber of the adjacent doublet. TEM taken on 4/21/88 by C. S...

A portion of an isolated cilium exposing two rows of outer dynein arms arising from subfiber A of each doublet. The heavy chains of the dynein complex are linked to the microtubule by stems that can b...
