Light acclimation strategies

Figures taken from Prezlin, Chapter 1 in Platt (1981) Physiological Bases of Phytoplankton Ecology.

Before and after low-light acclimation represented as photosynthesis per cell or per Chla.

Strategy 1: increase chla per PSU

 

Strategy 2: increase the number of PSU

 

Strategy 3: decreasing the efficiency of energy transduction within PSUs

 

Strategy 4: less C fixation
