Cells in these organisms contain special vesicles known as physodes [FY-so-deez]. They include the order Desmarestia, which dominates subtidal zones of the Antarctic region, the Ectocarpales, which contain heterotrichous thalli, and the Fucales, which reproduces in a manner similar to that of land plants. Another species is anchored by holdfasts and can grow to 100 meters. Also known as Phaeophyceae [fay-oh-FY-see-eh], they gain their color from the presence of fucoxanthin. For 10 points, name this class of algae that forms underwater forests, including the Laminariales, or kelp.
