This figure shows the connection between the peristome and the food vacuole forming zone where the alveoli end. The cytostome is the opening that connects these two zones. TEM taken on 6/13/69 by R. ...

Tetrahymena cells that are not forming a digestive vacuole often have a tube-like extension of the cytopharyngeal membrane attached to the deep fiber that extends several microns into the cytoplasm. T...

Two of the three types of vesicles that are transported to the cytopharynx and that accumulate in large numbers at the cytopharynx are shown in this electron micrograph. The discoidal vesicles move up...

11 micrographs are views of a serially-sectioned contracted Vorticella convallaria cell that show the main features of this cell. This figure shows 4 food vacuoles; 3 segments of macronucleus; cytopha...
