THE BEHAVIOR OF CHLORIDES IN THE CELL SAP OF NITELLA

THE BEHAVIOR OF CHLORIDES IN THE CELL SAP OF NITELLA 1. A method is given for determining the chloride content in a drop (less than 0.03 cc.) of the cell sap of Nitella . 2. Chlorides accumulate in the sap to the extent of 0.128 M ; this accumulation can be followed during the growth of the cell. The chloride content does not increase when the cell is placed for 2 days in solutions (at pH 6.2) containing chlorides up to 0.128 M. 3. The exosmosis of chlorides from injured cells can be followed quantitatively. When one end of the cell is cut off a wave of injury progresses toward the other end; this is accompanied by a progressive exosmosis of chlorides.

Abstract

1. A method is given for determining the chloride content in a drop (less than 0.03 cc.) of the cell sap of Nitella . 2. Chlorides accumulate in the sap to the extent of 0.128 M ; this accumulation can be followed during the growth of the cell. The chloride content does not increase when the cell is placed for 2 days in solutions (at pH 6.2) containing chlorides up to 0.128 M. 3. The exosmosis of chlorides from injured cells can be followed quantitatively. When one end of the cell is cut off a wave of injury progresses toward the other end; this is accompanied by a progressive exosmosis of chlorides. Footnotes Submitted: 20 January 1923
