Fig. 2: QF-DE of E-face of the cytopharynx membrane

The cytopharynx/nascent digestive vacuole (phagosome) has an E-fracture face containing a high number of IMPs. Interestingly these IMPs are sometimes organized into plaques (brackets) where there are several short rows of IMPs lying parallel to each other next to plaques with their rows of IMPs set at various angles to the other plaques. This suggests that each plaque is formed by the fusion of one discoidal vesicle and that the IMPs in the discoidal vesicles themselves must be organized into rows. EM taken on 5/26/92 by R. Allen with Zeiss 10A TEM. Neg. 19,800X. Bar = 0.2µm.
