There are about 1500 species of golden-brown
algae, which are all in
Class Chrysophyceae. This class of organisms is quite
diverse; some species have
flagella, others move like
amoebas, others don't move on their own at all. They
reproduce via
cell division, create food via
photosynthesis, and are characterized by having the
accessory pigment fucoxanthin.
