Membrane Electrical Behaviour in Nitellopsis Obtusa

The electrical properties of the two membranes, plasmalemma and tonoplast, bounding the cytoplasm of ' the brackish water characean, NitellopBiB obtUBa, were studied. In a solution approximating the natural pond water, the electrical potential difference between cytoplasm and outside was -141 mY, and between vacuole and cytoplasm +19 mY. The resistance of the plasmalemma was 80,000 n cms, and of the tonoplast, 10,000 n cm2
