PHAEPHYTA
Description: This phylum contains the brown algae, sargassum, and the various species of kelp. Brown algae are nearly all marine. Kelp blades can stretch up to 100 meters long. Brown algae have thin blades with a central midrib or stipe. Like all algae, their blades are thin because they lack the complex conductive tissues of green plants, and must rely on simple diffusion, though some kelp have phloem(green plant)-like conducting cells in the midrib.
