The oral region, illustrated here in a freeze-fracture image that passed through its left side, opens at the mid-ventral part of the cell. It consists of a funnel shaped vestibulum covered with regula...

CD3 mutant wheat (deficient in chlorophyll b was germinated and grown for 6 days in the dark, greened at high light intensity for 4 days in the presence of chloramphenicol, then prepared for thin sect...

This freeze fracture view of the pellicle of V. microstoma near the aboral end of the zooid shows the region where the width of each circumferential alveolus is narrower and thus the strings of fractu...

Freeze fracture of Vorticella microstoma. This cell had been placed in a relaxing medium of saturated sodium pyrophosphate plus 0.01M EDTA (Stain Tech. 47:37, 1972) for 3 hours. A myoneme enclosed by ...

Quick-freeze deep-etch image of rows of carrier vesicles lined up along the cytopharyngeal microtubular ribbons. These vesicles arise from early endosomes as clathrin coated vesicles and are about 100...

High resolution image of quick-freeze deep-etch of the P-face of the contractile vacuole. This face has many IMPs that are presumably transmembrane proteins many of which have been pulled free of the ...

High resolution image of quick-freeze deep-etch view of a radial arm showing a collecting canal surrounded with smooth spongiome as well as a few decorated tubules. However several larger vesicles lie...

The largest accumulation of endosomal vesicles and early endosomes is next to the buccal cavity area under the membranelles of the peniculi and quadrulus. Cilia of the peniculi have a very close packi...

Quick-freeze deep-etch of the P-face of the contractile vacuole. This face has many IMPs that are presumably transmembrane proteins many of which have been pulled free of the leaflet. There are also p...
