Phaeophyta or brown algae are a group of autotrophic, multicellular organisms, belonging to the class Phaeophyceae in the division Chromophyta. They contain the xanthophyll pigment - fucoxanthin, in addition to chlorophyll a and c. Hence, the members of phaeophyta exhibit a characteristic greenish-brown color.
All brown algae are all multicellular. In addition, they are the largest of the algae that possess chlorophyll c, growing to lengths of 45 meters or more.
