Crysophyta – The Golden Algae By Glenn Lippig
Some Members Dinobryon Synura Ochromonas Phaeoplaca Chrysophytes have varying life cycles since members are unicellular, colonial, or amoeboid, but most of them pass through a flagellate stage.
Key Features • Chrysophytes are facultatively heterotrophic (feed on bacteria/diatoms) in the absence of light • Most Crysophytes are unicellular, but some such as Dinobryn grow in colonies • Crysophytes are usually biflagellated (two flagella), but some have only one flagella and others are motile.
Chrysophyta are a foundation of the aquatic food chain in freshwater ponds and lakes.
Other Facts • Chrysophytes get their nickname “The Golden Algae” from their color, which is due to yellow and brown carotene and xanthophylls accessory pigments. • Chrysophyte cells can be “naked” and embedded in mucilage or “coccoid” and surrounded by a cell wall • There are over 1,000 species of Chrysophyta. • The ancestors of chrysophytes were actually not able to photosynthesize. It is believed they gained this ability through an endosymbiotic relationship with cyanobacteria.
