Xanthophyceae
Yellow-green algae or xanthophytes are an important group of heterokont algae. Most live in freshwater, but some are found in marine and soil habitats. They vary from single-celled flagellates to simple colonial and filamentous forms. Xanthophyte chloroplasts contain the photosynthetic pigments Chlorophyll a, Chlorophyll b, ?-Carotene, and the carotenoid . Unlike other heterokonts, their chloroplasts do not contain fucoxanthin, which accounts for their lighter color. Its storage polysaccharide is chrysolaminarin. Xanthophyte cell walls are produced of cellulose and hemicellulose. They appear to be the closest relatives of the brown algae. [more]
At least 558 species and subspecies belong to the Class Xanthophyceae.
