✦ Synopsis

Single giant cells of the algae Charu braunii and Nitella flexilis were exposed to bursts of electromagnetic radiation (monochromatic CW, bichromatic CW, or squarewave-modulated) in the band 200-1,000 MHz while their vacuolar potentials were monitored using micropipettes. The slow hyperpolarizing response that was observed seemed to be linear in the power deposited in the vicinity of the cell, to be otherwise indifferent to irradiation frequency or modulation, and therefore to be thermal in origin.

## Abstract Single giant cells of Chara braunii and Nitella flexilis were placed in a microstrip exposure apparatus and subjected to bursts of electromagnetic radiation (carrier frequencies from 200 to 8,200 MHz) at a nominal power level of 100 W/m^2^. The vacuolar potential was monitored with a mi
