In Ais paper, CO2 compensation levels and CO2 uptake in gas phase has been investigated for sev brown, green and red macroalgae. In order to get a better understanding of their systems for photosynthetic uptake of inorganic carbon (Ci), the measurements were carried out at different O2 concentrations.

Regarding cell structures, macroalgae are multicellular, photosynthetic marine oigan-isms which are similar to the land plants, but contain a leafthke thallus instead of roots, stems, and leaves. Taxonomically, they are divided up into the chlorophyceae een macroal e), rododphyceae (red macroalgae), and phaeophyceae (brown macroalgae) groups. The... 

Compared to studies on brown algae, and particularly on phlorotannins, only a few recent studies have explored chemical defenses in red and green macroalgae.
