Halicystis parvula
WebIon transport in the giant celled marine alga, Valonia ventricosa, was studied during internal perfusion and short-circuiting of the vacuole potential.The perfusing and bathing solutions were similar to natural Valonia sap and contained the following concentrations of major ions: Na 51, K 618, and Cl 652 m M.The average short-circuit current (I sc) was 97 pEq/cm 2 … WebUsing cultured cells of the marine alga, Halicystis parvula, the concentrations of 11 inorganic ions in the vacuolar sap and the electrical potential difference between the Vacuole and the external solution were measured and the volumetric elastic modulus of the cell wall was measured to measure the change in cell volume when the internal …
