Polarized light micrograph of a Diatom arachnoidiscus. Honorable Mention, 2010 Olympus BioScapes Digital Imaging Competition®.

Light micrograph of Volvox taken using Rheinberg illumination. Volvox form large (approximately 500 µm) spherical colonies that can contain up to 15,000 biflagellate, photosynthetic cells embedded i...

Higher resolution image 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 preendo...

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 spaced unevenly so they app...

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 surrounding a collecting...

In quick-freeze deep-etch preparations in which cells are slam frozen the pellicle and the plasma membrane tends to be flattened. The double rings are present but only the outer ring of IMPs stand out...

In a conventional freeze fracture view the membrane around the trichocyst tip is decorated with striations and IMPs. These decorations are found at the site where the trichocyst tip is associated with...

Freeze fracture image of the surface ridges at the anterior end of the cell where kineties to the right and left sides come together at an angle at the anterior suture tip. In this area are numerous p...

Conventional freeze-fractured images of DV-III membrane also suggests a transformation from a membrane with a smooth E-fracture face to one with characteristic large IMPs on its E-fracture face. The D...

Quick-freeze deep-etch image of a DV-III containing paracrystalline sheets in its lumen. The sheets have parallel rows of subunits spaced at 20nm center-to-center but the chemical nature of the sheets...
