  1. 20:3 Plant like Protists:Unicellular Algae • Plant-like protist are called algae • Can be unicellular or multicellular • Have chlorophyll or accessory pigments (other than green) Volvox is a colony of cells

  2. Examples of Algae • Euglenoids (unicellular) • Diatoms (unicellular) • Dinoflagellates (unicellular) “Red Tide”

  3. Algal Blooms • Excessive wastes cause the • Algae to flourish • Depletes water of nutrients • Algae die • Decomposition of algae robs the water of oxygen • KILLS FISH and other water life forms

  4. Multicellular Algae • Red (live in deep ocean) • Brown (giant kelp) • Green • volvox

  5. Importance of algae • Algae is the most abundant food source for the ocean • Called the ocean grasses • Contains Vitamins and Iron • Medicines (HBP, arthritis) • Food source • Chemicals from it are use in all levels of industry
