A high magnification view of the paracrystalline structure of the trichocyst tip and the cortex and core of the resting trichocyst body. Details of the sheath around the tip spike are also shown. (For...

Developing trichocyst containing a paracrystalline core surrounded by amorphous material and an autophagosome containing mitochodrion. TEM taken on 1/25/74 by R. Allen with Hitachi HU11A operating at ...

The infraciliary lattice in this quick-freeze deep-etched image consists of a meshwork of branching fibers composed of many subfibers. Basal bodies and trichocyst tips extend through the openings of t...

A favorable view of one trichocyst docking site in a quick-freeze deep-etch image shows the prominent outer ring of 37 IMPs and about the same number of IMPs in the inner ring more deeply embedded in ...

A higher magnification view that shows the bilayer nature of the ciliary membrane, plasma membrane and the outer and inner (alveolar sac membranes of the alveoli. The 9-doublet + 2-singlet microtubula...

A high magnification view of the paracrystalline structure of the trichocyst tip and the cortex and core of the resting trichocyst body. Details of the sheath around the tip spike are also shown. (For...

The P-face of the ciliary membrane at the base of the cilium has 9 triple rows of IMPs in register with the 9 doublets of the internal axoneme. It is thought that these IMPs may be sites of calcium in...

A high resolution micrograph showing four parasomal sacs in longitudinal section each at the base of a surface depression. Trichocysts extend into each lateral ridge (lateral ridges do not have kineto...

Four parasomal sacs showing them in longitudinal section each at the base of a surface depression. Trichocysts extend into each lateral ridge (lateral ridges do not have kinetodesmal fibers). Bulbous ...

Quick-freeze deep-etch images show a more three dimensional view of acidosomes surrounding a phagosome. Acidosomes are unique in that they contain indentations of their membrane. The lumen has a honey...
