Description

Freeze fracture of the plasma membrane and outer alveolar membrane of the pellicle of V. microstoma. The surface of Vorticella is encircled by rings which follow the septa of underlying alveoli. In this fracture one can see the fractured necks of the continuities between the outer and inner alveolar membranes (latter not visible). The outer alveolar membrane has many prominent IMPs on its P-fracture face. Septal pores extend between the continuities, thus the alveoli are all interconnected. The E-fracture face of the plasma membrane has only a moderate number of prominent IMPs compared to its P face. TEM taken on 11/11/75 by R. Allen with JEM 100B operating at 80kV. Neg. 14,579X. Bar = 0.25µm. A print of the negative was scanned and processed in Photoshop. This image is best used for qualitative analysis. There is a high resolution version of this image in the library (CIL:39325) which is available for quantitative analysis. Additional information available at (http://www5.pbrc.hawaii.edu/allen/).
