The detail of the three fibers supporting a basal body. A striated kinetodesmal fiber extends anteriorly from the basal body, a postciliary microtubular ribbon extends posteriorly and a transverse mic...

Detail of cell surface structures. The cell is covered by the plasma membrane and outer alveolar sac membrane which is separated from the inner alveolar sac membrane by an extensive alveolar space. Ci...

Nassula sp. Transmission electron micrograph of rows of cross-sectioned basal bodies at the cell surface. TEM taken on 3/4/69 by R. Allen with Philips 300 operating at 60kV. Neg. 16,000X. Bar = 0.5µm...

Endoplasmic reticulum, mitochondria with their tubular cristae and a Golgi stack. Ribosomes are scattered in the cytosol. TEM taken on 3/13/69 by R. Allen with Philips 300 operating at 60kV. Neg. 20,5...

Surface of Nassula aurea. Early endosomes and clathrin coated vesicles. One clathrin coated pit at the bottom of a parasomal sac is shown. TEM taken on 2/22/71 by M. Aihara with Hitachi HU11A operatin...

A high resolution image of the endoplasmic reticulum that exists in extensive sheets in the cytoplasm of Nassula immediately below the alveolar membranes. TEM taken on 3/14/69 by R. Allen with Philips...

Transmission electron micrograph of section through the macronucleus of Nassula sp containing many darkly staining nucleoli.

Detail of CV pore. Microtubules encircle the pore wall and other microtubules radiate out from the pore toward the CV membrane. TEM taken on 3/27/69 by R. Allen with Philips 300 operating at 60kV. Neg...

The top of the cytopharyngeal basket showing a closed cytostome where food will be engulfed. In the lab Nassula was fed Phormidium inundatum, a cyanobacterium. Ingested food is seen in food vacuoles a...

Tangential section through the anterior half of the cytopharyngeal basket. Drawings and discussion of the basket can be found in a paper by Tucker, J. Cell Science 3: 493-514, 1968. TEM taken on 4/1/6...
