Cytopharynx function

WebThe cytostome leads into a tubular canal, also called cytopharynx (gullet). The latter expands at the base to form a large rounded reservoir. At one end of the reservoir, the cytoplasm contains an orange red stigma (eye spot). The latter is photosensitive. WebMay 17, 2024 · (A) The cytostome-cytopharynx complex of epimastigotes is sustained by a microtubule triplet (green) that extends from underneath the cytostome membrane and a microtubule quartet (blue) that appears to start close to the flagellar pocket. It continues underneath the preoral ridge membrane [ 4 ].
