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...

This section represents one in a series of serial sections. At this point the two parts of the macronucleus are now connected by a DNA replication band similar to the hypotrichs (e.g. Euplotes). The l...

The contractile vacuole may evacuate through a CV pore located in an indentation of the pellicle not far from the adoral end. TEM taken on 3/18/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg...

This group represents a serial series of sections. At the level of this section, numerous food vacuoles, only three cross sectioned cilia remain of the perioral ciliature. TEM taken on 3/12/71 by R. A...

The cytosol contains numerous vacuoles as well as symbiotic bacteria (see Heckmann, Int. Rev. Cytol. 14(suppl.):111-143, 1983 for a discussion of symbiotic bacteria in Euplotes). TEM taken on 7/24/67 ...

In Euplotes a replication band of the macronucleus has larger heterochromatin masses on one side of the band after DNA replication has occurred. The replication band moves in the direction of lighter...

A view of the cytopharynx and its nascent food vacuole forming region. The flattened pharyngeal vesicles that may contain monolayers or bilayers of lipids seem to be equivalent to the discoidal vesicl...

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...

The images in this group show electron micrographs of epidermal and mesophyll cells in thin sections of maize leaves infected with Maize mosaic virus (MMV, Rhabdoviridae). MMV virions are bullet-shape...
