Question (Turpin): Does resource limitation (e.g. C, N, or P) constrain the ability of algal cells to undergo photoacclimation? Answer: Yes, resource limitation definitely constrains the photoacclimation response. The availability of N, for example, determines the cellular content of LHCPs. The paper by Chalup and Laws (1990) reveals how N availability modifies responses to irradiation. Question (Davison): Pronounced diurnal changes in irradiance occur in the natural environment, with morning and evening light levels typically being much lower than those at noon. Do algae change their photosynthetic apparatus in response to these changes? Answer: As we briefly discussed, algae do not photoacclimate at night; however, they do change their photosynthetic apparatus. Many algae become entrained in a circadian rhythm, where Chl/cell increases through the day and decreases close to the onset of night. This trait has been retained to some extent in higher plants. This cycle is exactly opposite to what would be expected if algae photoacclimate throughout the day. Rather, it would appear that algae respond to day-to-day variations in irradiance.
