Chrysophyta


Show Summary Details

Quick Reference

A large phylum of mostly freshwater algae that possess carotenoid pigments (responsible for their colour), in addition to chlorophylls. Their main storage products are oils and the polysaccharide chrysolaminarin. Most chrysophytes are unicellular, with two unequal-sized undulipodia (flagella), but some form colonies or are filamentous; one group of marine chrysophytes construct tests of silica. They are now classified as heterokonts.
