The term algae is a catchall for several evolutionary lines of photosynthetic organisms: dinoflagellates: red algae (plastids with chlorophyll A); diatoms, yellow-brown algae and brown algae (chlorophylls A and C); and green algae (chlorophylls A and B). This program explores the diversity, structure, ecological roles and modern classification of these vital primary producers.
