Abstract Photosynthesis in whole plants of Chondrus crispus Stackhouse was measured by 14C uptake under various light intensities and temperature regimes. In plants collected from waters of 6° to 7°C, photosynthesis did not increase with light intensity over a range of 200 to 2400 foot candles (ft-c). However, in plants collected from waters of 10° to 12°C, the rate of photosynthesis was lower over the range 200 to 1400 ft-c but, at 2000 ft-c, increased to a level similar to that of the 6° to 7°C plants. Ethanol-soluble and insoluble fractions showed similar patterns.
