High resolution image of cilia and cytopharyngeal vesicles containing a flocculent content of unknown composition which lie next to the cytopharynx and between the buccal cavity and what may be the n...

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...

This image of Halteria was fixed in cacodylate-buffered fixative and stained. The round, dark bodies, possibly pigment granules, were transparent in other preparations are electron-opaque following th...

The DNA replication band in macronucleus of Halteria. Like hypotrichs the macronucleus of this oligotrich has a DNA replication band where DNA is synthesized. The nucleolus is evident. TEM taken on 3/...

High resolution image of Halteria showing the extension of buccal cavity and the cytopharynx passing into the cell. Vesicles accumulate at the cytopharynx next to the lamellae. These vesicles may be h...

An image of cilia and cytopharyngeal vesicles containing a flocculent content of unknown composition which lie next to the cytopharynx and between the buccal cavity and what may be the nascent food v...

This group represents a serial series of sections. At the level of this section, a little deeper in the cell the spongiome of the CV is more pronounced. Oral membranelles in the buccal cavity are indi...

This group represents a serial series of sections. At the level of this section, the macronucleus and micronucleus are present. The buccal cavity with cilia and the spongiome of CV, membranelles of pe...
