17.5: Phaeophyta - The Brown Algae - Biology LibreTexts
WEBBrown algae are brown due to the large amounts of carotenoids they produce, primarily one called fucoxanthin. These organisms are exclusively multicellular and can get so large that they require special conductive cells to transport photosynthates from their blades down to the rest of their tissues.
