Larger vesicles contain paracrystalline cores that are associated at one end with the trichocyst membrane. This may mean that there is a site on the membrane that promotes paracrystalline formation or...

Released from the cell the trichocyst lengthens and its internal meshwork opens up into an elongated needle. TEM taken on 6/7/88 by C. Schroeder with Zeiss 10A operating at 80kV. Neg. 24,880X. Bar = 0...

A view of microtubular ribbons in which the periodic structure of the tubulin units can be seen along the length of the microtubules. Short bridges link the microtubules side to side within a ribbon. ...

A row of large IMPs bordering parts of the plates are visible. Two parentheses-shaped empty trichocyst docking sites are also present and one ring surrounding pits where the rosette IMPs have been rem...

Views of a striated band linked to the epiplasm on the ridge slopes and the intermembrane space between the plasma membrane and alveolus space inside the alveolus. TEM taken on 6/6/91 by C. Schroeder ...

Scanning probe 3D image of a single metaphase wheat chromosome, with selected height contours superimposed around the base. Using such images, complete genomic sets of chromosomes can be classified ac...
