High magnification view of a crushed mitochondrion showing the zipper-like row of 9nm diameter particles on the outer curve of the cristae and the single row of larger particles on the inner curve. Th...

High resolution image of vesicles and early endosomes under the membranelles of the peniculus of the buccal cavity. Cilia and basal bodies are tangentially fractured in this quick-freeze deep-etch pre...

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 be pinched off from the ea...

This freeze fracture view of the pellicle of V. microstoma near the aboral end of the zooid shows the region where the width of each circumferential alveolus is narrower and thus the strings of fractu...

Acidosomes originate from the biosynthetic pathway that includes the ER, the Golgi stack and the trans-Golgi network (TGN). Flattened vesicles from the TGN round up into spherical vesicles and bind to...

Quick-freeze deep-etch image of two decorated tubules with helically wound subunits on their cytosolic surfaces. Each step in a helical turn appears to be formed of three dyads lying side by side acro...
