SYNOPSIS. Response of Chlamydomonas to temperature change was investigated. When the temperature of the medium was suddenly increased (decreased) the abrupt velocity rise (drop) was observed. This abrupt velocity change was induced immediately after the temperature change. Then, the high (low) level of the velocity was maintained for a few minutes. Finally the velocity decreased (increased), tending to a stationary level at the new temperature with the decay time of a few minutes. The rate of the temperature change determined the magnitude of response. The threshold value was found in the rate of the temperature change to produce the transient change of the velocity. It was ∼ 0.2 C/sec.
