What accessory pigments do cyanobacteria have?
Carotenoids and phycobilins
What accessory pigments do Red algae have?
Phycobilins
What accessory pigments do plants and green algae have?
Carotenoids.
What are the two types of Phycobilins?

What organisms have 3 membrane chloroplasts?
Euglenoids.
What’s special about Cryptamonids?
They are algae with a nucleomorph.
What 3 types of organisms have 4 membrane chloroplasts?
Diatoms, brown algae, and dinoflagellates.
How were stamenopiles derived?
One secondary event involving a red algae.
What accessory pigments do Diatoms have? What does it do?
Fucoxanthins, which make them look brown.
What chlorophylls do diatoms have?
Chlorophyll a and c.
What are the walls of diatoms made up of?
Glass.
How were brown algae derived? What else resulted from this event?
One secondary event involving a red algae along with diatoms.
How were dinoflagellates derived? Were any other organisms derived during this event?
Dinoflagellates were derived From a secondary endosymbiosis event with a red alga different from that of the diatoms and Brown Algae.
What chlorophylls do dinoflagellates have?
Chlorophyll a and c.
What’s special about the genus of the dinoflagellates, Symbiodinium?
It forms a symbiotic relationship with the stony corals.
What chlorophyll do red algae have?
Chlorophyll a.
What accessory pigments do red algae have?
Phycobilins.
What allows red algae to grow deep in water?
