  3. Five Supergroups Excavata Euglenoids Dinoflagellates, diatoms, golden and brown algae Chromalveolata Rhizaria Forams and radiolarians Archaeplastida Red and green algae Unikonta Slime molds

  4. Volvox Spirogyra

  5. Chlamydomonas

  6. Dinoflagellates Diatoms Chlorophyta (green algae) Phaeophyta (brown algae) Rhodophyta (red algae)

  7. Phylum Pyrrophyta: dinoflagellate • Single-celled eukaryote • Animal/plant type organism with 2 flagella • Bioluminescence • Zooxanthellae: Symbiodinium Ceratium

  8. Phylum Bacillariophyta: Diatoms Thecate- with shell Athecate- naked 2 kinds: centric (circular) and penate (oblong) Frustule (silica shell) pennate centric

  9. Diatom Reproduction- asexual epithecate hypothecate auxospore Discards shell and grows new one

  10. Chlorophyta: Green Algae Halimeda opuntia Caulerpa sertularioides Codium edule Caulerpa racemosa Dictyosphaeria cavernosa

  11. Phaeophyta: Brown Algae Padina japonica Turbinaria ornata Hydroclathrus clathratus Sargassum echinocarpum Sargassum polyphyllum

  12. Kelp

  13. Rhodophyta: Red Algae Hypnea chordacea Ahnfeltia concinna Acanthophora spicifera Galaxaura fastigiata Asparagopsis taxiformis

  14. Algal Products • Thickener and help smooth: • Many foods and milk-products Certain alga can be used to make agar or as stabilizer in gelatin and ice cream: Use: sugar, milk, irish moss or euchima, Chondrus, Porphyra and Rhodymenia- blend and boil. • Toothpaste • Beauty creams • Paints • Medical products- like bacterial culture plates, time-release pills, and dental impression gels
