Crysophyta – The Golden Algae

By Glenn Lippig


Some members

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

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.


Crysophyta the golden algae

  • Chrysophyta are a foundation of the aquatic food chain in freshwater ponds and lakes.


Other facts

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.
