Abstract
The photosynthetic acclimation of the red macroalgae Gracilaria tenuis tipitata at high and low external inorganic carbon concentration (Ci) resembles the characteristics of ''shade'' and ''sun'' adapted plants respectively, showing higher photosynthetic rates at low- than at high -Ci. However the photosynthetic efficiency is higher in the low-Ci alg ae which present a higher pigment content. The influence of inorganic carbon concentration on the levels of photosynthetic pigments and the possible CO2 control over photosynthetic apparatus is discussed.
