Chrysophyta

a division of the algae. The colouring is caused by the presence of CAROTENOID pigments that are present with the CHLOROPHYLL. This very diverse group of freshwater and marine forms includes the golden-brown algae (Chrysophyceae), yellow-green algae (Xanthophyceae) and the diatoms (Bacillariophyceae).
