Algae Classification
   •   Algal classification is based on type of photosynthetic pigment present.
   •   Three categories of algae are
         • Chlorophyta - Green algae (Chlorophyll a & xanthophylls) - Spirogyra
         • Phaeophyta - Brown algae (Chlorophyll a, b & fucoxanthine) - Sargassum
         • Rhodophyta - Red algae (Chlorophyll a, Phycocyanin & Phycoerythrin) - Porphyra
Algae Classification
   They can be grouped by sizes
        • Macroalgae (seaweeds)
             - multicellular, large, and can be seen with the naked eye.
        • Microalgae
             - are unicellular, smaller in size, and can only be seen microscopically.
