Chloroplasts contain photosynthetic pigments (Chl- a, b, carotenes and xanthophylls) similar to those of land plants. So, when we talk about forests of brown algae, we really mean vast underwater forests. High concentrations (in excess of 2 mg/L above the oxidative demand) may be harmful to fish and other aquatic organisms.
