Cyanobacteria |
Prokaryoyotes
Pigments: Chlorophyll a, Phycobilins (red and Blue) Photosynthesize, produce O2 May fix N2 in heterocysts Recombination but no mitosis, Meiosis No flagellae but some move Ecology Ponds, oceans, hotwater |
Prochlorophytes |
Prokaryotes
Pigments: chlorophyll a,b, No phycobilins(red and blue) |
Chlorophyta (green Algae) |
Unicells, fillament, sheets, colonies, sphere, stars
Freshwater, marine, wet films, symbionts Pigments: Chl a,b, carotenoids Store food as starch Cell walls: cellulose Sexual and asexual reproduction Variations a. Unicellular Motile:chlamydomonas, chlorella Desmids: star shaped or crescent shape Acetabularia b. Filamentous Spirogyra Oedogonium hydrodietyon c. Colonial (multicelluar) Ulva Volvox d. Coenocytic Codium |
Phylum Chromophyta (Kingdom chromista)

Elongated unicell with felxivle pellicle
Food groove Chloroplasts or not One flagellem has hair fringe, other has eyespot |
Dinophyta: Dinoflagellates |
Covered with cellulose plates
Two flagellae Many have chlorophylls a,c, xanthophylls lots of condensed DNA Bioluminescent Ecology: Warm marine Red tides |
Pryhmnesiophyta: Haptophytes

Small unicells with 3 flagellae
3rd flagellum +for food capture Chromophyte pigments: Chlorophyll a, carotenoids, xanthophylls most covered with calcified plates Ecology: Plantonic marine |
Charophyta: Stoneworts |
Slender stalk with whorls of branches
Green algal pigments: Chlorophylls a,b Often calcified surfaces carotenoids |
